🚨 A hydrogen engine just hit 60% efficiency — with near-zero emissions. That’s diesel-level power… without the pollution. But here’s the twist: It’s not just burning hydrogen. It’s using a closed-loop system with: • Hydrogen → energy source • Oxygen → reaction control • Argon → stabilizer (doesn’t react) Most of the gas is reused every cycle So instead of dumping exhaust… It recycles the system internally Why this matters: • Heavy transport (trucks, ships, machinery) can’t easily go electric • Hydrogen solves energy density — but stability was the issue • This design fixes that by controlling the thermodynamics My take: This is the same pattern we’re seeing everywhere: Not just new fuels… But controlled environments that maximize efficiency Energy isn’t just about what you use. It’s about how you structure the system Follow me I track where physics becomes structure.

What Looks Like A Complex Set Of Spinning Parts Is The Core Of How Trucks Convert Engine Power Into Motion. A drivetrain system transfers torque from the engine through the transmission, driveshaft, and differential to the wheels. Each component plays a specific role. The transmission adjusts torque and speed, the driveshaft carries rotational force, and the differential distributes power between wheels while allowing them to rotate at different speeds during turns. Seeing the system in motion reveals how precisely synchronized these components must be to handle heavy loads and maintain efficiency under stress. In Heavy Vehicles, Power Is Only Useful When It Is Controlled.

🚨The energy crisis triggered by the Persian Gulf conflict is accelerating the shift to a multipolar world. 🇷🇺🇨🇳Russia and China are building a parallel energy system less dependent on Western finance, shipping, and payments. This accelerates de-dollarization through energy trade in national currencies, energy economist Dr Kazi Sohag told Sputnik. 🔸China is becoming the Global South’s main guarantor of energy security through its dominance in green technologies — solar, batteries, EVs, grids, and storage. 🔸Via the Belt and Road Initiative, China offers complete turnkey solutions — hardware, financing, construction, and rapid deployment — at prices and scale the West cannot match. 🔸Amid global scarcity, Russian oil becomes far more attractive, strengthening their bargaining power with India, China, and other major buyers. This weakens Western sanctions as importers prioritize physical supply over compliance. 🔸The energy crisis exposed Western vulnerability to physical supply shocks and the limits of sanctions, proving that financial power alone cannot guarantee energy security. 🔸As a result, Russia strengthens its role as a key hydrocarbon supplier, while China accelerates its leadership in clean energy. Together, they are speeding up multipolarity by encouraging countries to diversify away from exclusive Western systems.

This video shows a static fire test of the Archimedes rocket engine, developed by Rocket Lab. Archimedes uses liquid methane (LCH.) as fuel and liquid oxygen (LOX) as the oxidizer, a combination known as methalox. During combustion, these cryogenic propellants produce extremely high temperatures (over 3,000°C), hotter than lava. To survive this, the engine circulates cold fuel through its walls before burning it, a technique called regenerative cooling. Multiple Archimedes engines will power Rocket Lab's upcoming Neutron rocket, which is being built to launch satellites and cargo to orbit with lower cost and higher reliability. Rocket Lab is best known for its Electron rocket and is now expanding into larger, reusable launch vehicles with Neutron.

🚨 THE ENERGY TECHNOLOGY THAT COULD POWER CIVILIZATION FOR THE NEXT 100 YEARS ISN'T FUSION. Molten Salt Reactors use molten fluoride or chloride salts as coolant and in some designs, the nuclear fuel itself is dissolved directly into that salt. This is very different from traditional reactors. Instead of solid fuel rods sitting in water under high pressure, these systems run at much higher temperatures but at atmospheric pressure, which dramatically reduces the risk of explosions or meltdowns. The salt can flow over solid fuel, or the fuel can be mixed directly into the coolant. Both approaches are being actively developed. Why this matters: • MSRs operate at high temperatures, making them potentially much more efficient at generating electricity and process heat • Low-pressure operation makes them inherently safer than conventional water-cooled reactors • Some designs can burn existing nuclear waste or use thorium as fuel • The technology could support everything from advanced power generation to hydrogen production and industrial heat The deeper implication: For decades, nuclear power has been dominated by one basic design concept. Molten salt reactors represent a fundamental rethink using a liquid that can act as both coolant and fuel. This opens the door to reactors that are safer, more flexible, and potentially capable of solving some of nuclear energy’s biggest historical challenges (waste, fuel efficiency, and public perception of safety). While still in development, MSRs are one of the most promising pathways for next-generation nuclear power. We may be looking at the early stages of a genuinely new chapter in how humanity generates clean, reliable energy. Do you think molten salt reactors will become a major part of the future energy mix, or will traditional designs continue to dominate?

🇺🇦 The Ukrainian Ministry of Defense has officially codified and adopted into service the armored vehicle MAC OWL, produced by the Ukrainian company MAC HUB. It was first publicly presented at the beginning of this year. 🔻 The MAC OWL was developed in cooperation with the South African company Paramount Group and is essentially the Ukrainian-adapted version of the South African Mbombe 4 armored vehicle. 🔻 The vehicle’s protection level meets NATO standard STANAG 4569 Level 4 (capable of withstanding 14.5mm bullets) and weighs 16 tons. Despite its weight, it can reach a maximum speed of 100 km/h, thanks to a 450 hp engine. The crew consists of 3 servicemen and it can transport an additional 6 fully equipped soldiers. 🟧 It will be equipped with a remotely controlled combat module armed with either 12.7mm M2 Browning machine guns or 40mm automatic grenade launchers (MK-19 or UAG-19). The adoption of the MAC OWL is a significant achievement for Ukraine’s defense industry. By localizing the production of a modern, well-protected armored vehicle based on proven South African technology and adapting it to local conditions, Ukraine is strengthening its own armored capabilities and reducing dependence on foreign supplies. This vehicle is well-suited for the realities of the current war. Video is generated by grok AI

🇨🇳🇺🇲CHINA says New Y-30 Transport Will Outperform U.S. C-130J in Payload and Power. China's state-affiliated media and a recent analysis in Aerospace Knowledge (published by Beihang University) have highlighted the Y-30 as a next-generation medium-lift tactical transport aircraft intended to outperform the Lockheed Martin C-130J Super Hercules in several key areas. The Y-30 is a four-engine turboprop developed by Shaanxi Aircraft Industry Corporation (under AVIC). It completed its maiden flight in December 2025 and remains in the early prototype/testing phase, with no publicly confirmed production schedule or final operational specifications from official Chinese sources. According to the Chinese analysis, the Y-30 is positioned to surpass the C-130J in: 🔺️Engine power — Powered by four indigenous AEP-500 (or EP-500) turboprops, claimed to deliver significantly higher output than the C-130J's Rolls-Royce AE2100D3 engines. 🔺️Payload capacity — Targeted at around 30 tonnes (some reports mention up to 35 tonnes in certain configurations), compared to the C-130J's typical maximum payload of roughly 19–21 tonnes. 🔺️Structural design and materials — Extensive use of composites for reduced weight and improved strength, versus the C-130's more traditional all-metal airframe. 🔺️Avionics and flight control software — Modern integrated systems offering potential advantages in automation and performance.

🚨🇷🇺 WEST SHOCKED: RUSSIA JUST BUILT ITS FIRST CHIP MACHINE The West tried to cripple Russia with sanctions and cut off advanced chips. But Moscow just put its very first domestic photolithography machine — the Progress STP-350 — on open sale for about 400 million rubles. 🔸 This machine makes 350nm chips — bigger, tougher transistors that are perfect for military use. They resist radiation, Electromagnetic Pulse (EMP) attacks, extreme heat/cold, vibration, and high voltage (up to 100V) where super-small modern chips fail. 🔸 Perfect for triple-redundant military circuits (three copies of the same chip working together) that never fail even if one gets hit by cosmic rays or EMP pulse. 🔸 Handles extreme battlefield conditions: huge temperature swings, constant vibration, high voltage up to 100 Volts — things impossible on modern super-thin processes. 🔸 Uses a modern solid-state laser (365 nm) instead of old mercury lamps. It can process up to 63 silicon wafers per hour (150-200 mm size) and lasts much longer — up to 10,000 hours. 🔸 Developed since 2021 with help from Belarus company Planar — cutting Russia’s tech gap from 40-50 years down to about 30 years. 🔸 Ideal for critical defense systems: control units, engines, power supplies in missiles, planes, and radars that need reliability first, not maximum speed. 🔸 Foreign versions cost 2-3 times more. Tiny modern nodes are perfect for phones, but terrible for military use. 350nm is a mature, battle-proven tech that delivers superior reliability, radiation resistance, high voltage tolerance, and durability — exactly what defense systems and civilian sectors (cars, medicine, comms) actually need. Did Western sanctions actually make Russia stronger?

We continue to analyze the technical details of the war with Iran, and we would like to note the Iranian novelty - subsonic barraging anti-aircraft missiles Missile 358, equipped with compact turbojet engines. To some extent unexpectedly, they showed good effectiveness against Israeli reconnaissance and strike UAVs Hermes-900. The key role is played by the thermal homing head: it is able to reliably detect and track a wide range of heat-contrasting targets, including UAVs with various flight profiles. An additional advantage is the command and telemetry channel, which ensures data transmission and allows for radio correction of the trajectory. This is especially important in situations when the target attempts to disrupt the capture with infrared decoys or other means of counteraction. According to the stated parameters, the range of application of Missile 358 reaches about 100 km. At the same time, the maximum interception altitude is about 8.5 km, and the speed is up to 700 km/h, which expands the capabilities of the complex in covering objects and intercepting medium-altitude UAVs. Of course, this is a niche tool, and compared to solid-fuel missiles, the turbojet engine provides exponentially higher flight energy. This allows to dramatically increase the range at low speed, and the mass of the main units of the ammunition, its warhead and control system. On the other hand, this is a solution of necessity, because classic anti-aircraft missiles perfectly hit such high-altitude and slow-moving targets. But for such ammunition, no radar, complex and expensive beam installations are required, which greatly improves its survivability under constant air strikes. And in its niche of targets, there are enough of them, as such UAVs of Israel and the USA are the basis of UCAV, and are constantly over the territory of Iran. So with the 358th ammunition, you can score quite a lot of frags, and significantly complicate air strikes on Iran for the Epstein coalition. Russian Engineer -

This looks like a regular IT server room. But it is actually the main avionics compartment of an Airbus A350, a rare view into what sits at the very front of the aircraft, directly beneath the cockpit floor. Inside are 22 purpose built computing modules made by Thales, each costing more than $100,000+ They host multiple aircraft systems, processing everything from flight controls and landing gear to hydraulics, fuel, electrical systems and flight warnings. All of them are connected through a dual redundants AFDX network, with 14 switches and 29 remote data concentrators distributed throughout the aircraft. Keeping this computing architecture running requires an estimated 50-60+ kW of electrical power. The electricity keeping all of this computing hardware alive is generated in real time from the aircraft's two engines. Each engine mechanically drives two generators through its accessory gearbox, giving the A350 four generators capable of producing up to 100 kVA each. That electricity then flows through the aircraft's power network, where transformers and rectifiers convert it into the different AC and 28 V DC supplies the avionics need. And if those generators fail, the aircraft has layers of backup power, including the APU and, in an extreme emergency, a ram air turbine that deploys automatically if all systems fail. The A350 has two independent avionics cooling circuits, heat extraction fans and backup airflow paths to keep the computers within their operating limits. So the next time you hear the word autopilot, remember what it really takes to make an Airbus A350 fly itself, An entire architecture of computers, networks, redundant power and cooling, hidden beneath the floor where no passenger ever sees it.

When a spacecraft leaves Earth, it doesn’t just fire its engines and head straight to its destination. In many missions, especially those going beyond low Earth orbit, there’s a more subtle and elegant strategy at play, one that uses gravity itself as part of the navigation system. This is often called a gravity assist, or a slingshot maneuver. But in the case of missions like #Artemis II, what’s being used is a closely related idea known as a free-return trajectory. At first glance, it might sound simple: the spacecraft goes to the Moon, loops around it, and comes back. But the physics behind it is anything but simple. Instead of relying on continuous propulsion, the spacecraft follows a carefully calculated path through the gravitational field of the Earth–Moon system. It is launched with just the right speed and direction so that, as it approaches the Moon, the Moon’s gravity bends its trajectory. The spacecraft is effectively flung around the Moon, redirected onto a path that naturally brings it back toward Earth. No major engine burn is needed for the return. Small trajectory corrections may still be required, but gravity does the heavy lifting. That’s the key. This kind of trajectory is not just efficient, it’s also safe. If something goes wrong with the spacecraft’s engines or onboard systems, gravity itself ensures the return. It’s an inherent backup plan, built into the trajectory from the very beginning. The same fundamental idea appears in gravity assists used across the Solar System. When a spacecraft flies past a planet, it can gain or lose speed by exchanging momentum with that planet. From the spacecraft’s point of view, it’s as if it has been accelerated without using fuel. In reality, it has borrowed a tiny amount of orbital energy from the planet itself. That’s how missions like Voyager reached the outer planets, and how probes continue to explore regions far beyond what their onboard fuel alone would allow. But there’s an important distinction. An interplanetary gravity assist is typically used to change speed and direction, often increasing the spacecraft’s energy. A free-return trajectory, like the one used in Artemis II, is designed for something more specific: a path that naturally loops back to Earth without requiring additional propulsion. It’s less about gaining energy, and more about shaping a trajectory that guarantees a return. To understand why this works, it helps to stop thinking in straight lines. In space, motion follows curves defined by gravity. The spacecraft is constantly falling, first toward Earth, then toward the Moon, and then back toward Earth again. What looks like a loop is really a continuous free fall through a changing gravitational landscape. This way of navigating space reveals something deeper. We tend to think of engines as the drivers of motion, but once a spacecraft is on its way, gravity does most of the work. The art of spaceflight is not just about thrust. It’s about knowing when not to use it. #GoodLuck #Artemis NASA Artemis

In 1963, the U.S. Navy wanted to find out if a standard Marine Corps KC-130F Hercules, a massive 40-ton cargo plane, could land on a moving aircraft carrier to deliver heavy supplies over long distances. The ship was the USS Forrestal. And the pilot was Lieutenant James H. Flatley III, who had actually never flown a four-engine aircraft before getting this assignment. The Hercules had absolutely no tailhook, meaning it couldn't use the ship's arresting wires to stop. To land, the carrier had to steam at max speed directly into the wind, generating a massive 40-to-50-knot headwind down the deck. And the moment the tires touched down, Flatley had to slam all four engines into full reverse thrust bringing the giant plane to a complete halt in just 267 feet. Its massive 132-foot wingspan cleared the ship's control tower island by less than 15 feet. But taking off was an even crazier physics problem as the C-130 was way too big to hook up to the ship's steam catapults and therefore had to launch entirely under its own power. The crew thus had to back the aircraft up to the absolute rear edge of the flight deck. Flatley locked the brakes down completely and revved all four turboprop engines to 100% maximum power. When he released the brakes, 20,000 horsepower launched the plane forward. While Flatley focused on nose-wheel steering to keep the plane straight, his co-pilot held the control wheel to keep the massive wings level. Combined with the heavy headwind, the C-130 generated so much lift that it soared off the deck in only 745 feet. Over three days, they completed 29 touch-and-goes, 21 full-stop landings, and 21 unassisted takeoffs. Even though it worked, the Navy ultimately scrapped the idea as the C-130 was so huge it couldn't fit down the carrier's elevators, and the crew had to clear the entire deck just to land it; completely paralyzing the ship’s combat mission.

🚨 NASA-BACKED CONCEPT SHOWS A 100+ SEAT AIRLINER THAT COULD BE UP TO 17% MORE EFFICIENT THAN FUTURE PROJECTIONS. Electra has unveiled a new turbo-electric aircraft concept developed under NASA’s AACES 2050 program. The design uses a double-bubble fuselage and electrically driven tail fans to recover energy from the airflow that normally trails behind an aircraft. Two conventional turbofan engines under the wings generate electricity, which powers fans mounted at the rear. These fans ingest and re-energize the slow-moving boundary layer air flowing over the fuselage a technique known as boundary layer ingestion. This reduces wasted energy in the aircraft’s wake. Why this matters: • The concept is designed to fit within existing airport infrastructure and airline operations • It doesn’t require new charging stations or alternative fuels it can run on jet fuel or sustainable aviation fuel • The double-bubble fuselage generates more lift from the body itself, allowing a twin-aisle cabin in a narrower overall aircraft • The study suggests up to a 17% efficiency gain beyond what’s already expected from future improvements in engines, structures, and aerodynamics The deeper implication: Most future aircraft concepts focus on either radical new propulsion (like hydrogen or all-electric) or incremental improvements to conventional designs. This concept takes a middle path using electrification not to replace engines entirely, but to unlock aerodynamic improvements that were previously impractical. It shows how hybrid-electric systems could help bridge the gap between today’s aircraft and much more efficient future designs.

The problems in Russia’s oil and gas sector are already becoming systemic. Russia is refining less oil, transporting it at a higher cost, facing problems with export infrastructure, and already losing oil and gas revenues. Let’s take a look at what exactly is happening inside Russia. First, the Russian authorities themselves are no longer treating the shortage as a short-term disruption. A complete ban on diesel exports was introduced in early July, and it is quite likely to be extended through the end of the year. Gasoline exports are banned until January 31, 2027, and jet fuel exports until the end of November. Russia has also started importing additional petroleum products from Asia and Belarus. Second, Russia is physically refining less and less oil. According to Kpler, Russian refineries processed around 3.8 million barrels per day in July - the lowest level in more than two decades. EA Analytics estimates the figure even lower, at approximately 3.6 million barrels per day. For comparison, the normal level for this period in 2020-2025 was 5.3-5.6 million barrels per day. Third, Ukrainian strikes on Russian oil refineries are continuing. A cycle has effectively formed: strike - repairs - partial recovery - another strike. Following the August 21 attack, the Perm Oil Refinery, with an annual capacity of 13.1 million tonnes, was completely shut down. Since August 2025, at least 25 Russian oil refineries have been targeted. Fourth, the diesel shortage is making the economy more expensive - increasing the cost of harvesting, reducing the resilience of Russia’s logistics system, and consequently affecting prices overall. Fifth, even the oil Russia manages to produce is becoming more difficult and expensive to export. In the first half of August, exports from western ports amounted to around 2.3 million barrels per day instead of the planned 2.7 million. Novorossiysk was particularly affected: shipments fell to around 400,000 barrels per day, compared with 800,000-1 million in June-July. Previously, problems at refineries could be partially offset by increasing crude oil exports. But when refineries, ports, terminals and tankers are all being targeted simultaneously, this becomes much harder. Exports have not collapsed, but they have become more expensive and less predictable. The same applies to petroleum products: in July, seaborne exports of fuel oil and vacuum gasoil fell by around 12%, to 2.4 million tonnes. The situation with gas is structurally worse. The Power of Siberia pipeline has already nearly reached its contractual ceiling - around 38.8 billion cubic meters per year. Power of Siberia 2 is primarily constrained by price: China wants gas at a significantly lower price than Russia is willing to sell it for. LNG faces even more problems: the EU has already begun phasing out imports, while redirecting supplies to Asia means longer and more expensive logistics. China is increasing its purchases of Russian gas, but it has not replaced Europe and will not replace it quickly. The most serious problem is the budget. In the first half of the year, Russia’s oil and gas revenues fell by 22.7% year-on-year, and by 16.8% over the first seven months. By January-April alone, the federal budget deficit had reached 5.88 trillion rubles, exceeding the planned deficit for the entire year. On top of this come the costs of refinery repairs, air defense, fuel imports, alternative routes, freight and insurance. Despite all these losses, we can see that Russian oil and gas revenues have not yet collapsed, although adaptation is becoming increasingly expensive. For now, the Kremlin is being helped by the crisis around the Strait of Hormuz, which is keeping oil prices high. At the same time, Russia’s ability to refine and export this oil is deteriorating. So far, high prices are offsetting these losses. If the situation around Hormuz stabilizes and Brent prices fall, the current logistical and fuel problems could become much more serious for Russia.

🚨 SPACEX IS ABOUT TO TEST A RADICALLY DIFFERENT KIND OF SPACECRAFT AND IT COULD UPEND THE ENTIRE ORBITAL MANUFACTURING INDUSTRY. On Tuesday, SpaceX plans to fly the first prototype of Starfall, a flat, disk-shaped reentry capsule designed to return up to 1,000 kilograms of cargo from orbit in a single flight. That’s roughly 30 times more payload capacity than current commercial return vehicles (like those from Varda Space Industries). It’s not a scaled-down Dragon it’s a completely different approach: no onboard deorbit engine, a wide flat disk geometry, and Starlink terminals mounted to maintain communication through the plasma blackout during reentry. Why this matters: • Current orbital manufacturing companies are limited to returning only dozens of kilograms per mission • Starfall’s design could make large-scale commercial production in space economically viable for the first time • SpaceX would be directly competing with companies (like Varda) that currently pay SpaceX to launch their capsules • Successfully testing Starlink through reentry plasma would be a major technical win with applications across SpaceX’s vehicles The deeper implication: SpaceX is quietly expanding its vertical integration. They already dominate launch. Now they’re moving into the return leg of the orbital manufacturing supply chain the part that has been the biggest bottleneck for companies trying to make products in microgravity and bring them back to Earth. If Starfall works at scale, it doesn’t just give SpaceX another revenue stream. It gives them significant control over the economics of an entire emerging industry. The disk shape and high-capacity design suggest they’re thinking about high-cadence, lower-cost returns rather than the traditional high-value, low-volume approach. This is classic SpaceX: take an existing problem (expensive, low-capacity return from orbit), apply first-principles thinking to the vehicle design, and try to make it dramatically cheaper and higher volume. How do you think this move into orbital return changes the competitive landscape for companies trying to build businesses in space manufacturing? Follow for more analysis on SpaceX’s expanding role across the space economy.

The Russian FAB-3000 with Extended 200 km Glide Kit: A Devastating Precision Weapon The FAB-3000, or Fugasnaya Aviabomba 3000, represents one of Russia's most formidable unguided aerial bombs from the Soviet era, now revolutionized by modern glide kits. Originally developed in the 1950s as a high-explosive demolition weapon, the FAB-3000 weighs approximately 3,000 kilograms (6,614 pounds), with a length of 3.84 meters and a diameter of 680 millimeters. Its warhead contains about 1,370 kilograms of TNT or a similar high-explosive filler, capable of generating a blast radius exceeding 200 meters and penetrating up to 1.5 meters of reinforced concrete. Designed for strategic bombing, it was historically dropped from heavy bombers like the Tu-22M3, but its revival in contemporary conflicts stems from integration with advanced guidance systems. The key transformation comes from the Universal Module for Planning and Correction (UMPK), a tail-mounted kit produced by Russia's Bazalt Design Bureau. The standard UMPK equips the bomb with folding wings spanning up to 3 meters when deployed, a streamlined fairing for aerodynamic stability, and a satellite-navigation system using GLONASS for mid-course corrections. This converts the inert FAB-3000 into a standoff glide bomb, extending its effective range from a mere free-fall drop to 50-60 kilometers when released from altitudes of 5,000-12,000 meters. Guidance achieves a circular error probable (CEP) of 10-30 meters, allowing strikes on bunkers, fortifications, and urban targets with minimal collateral risk compared to unguided variants. The kit adds roughly 200-250 kilograms, including control surfaces and inertial sensors, and is compatible with Su-34 fighter-bombers, which carry it externally on the centerline pylon. Recent upgrades have pushed the envelope further with the jet-powered UMPK-PD variant, achieving an extended range of up to 200 kilometers. This iteration incorporates a compact turbojet engine—sourced from commercial Chinese suppliers like the SW800Pro-Y—mounted in a tubular rear section, providing thrust for powered gliding. The design features enhanced aerodynamics with a curved, sloping tail and lighter composite materials, reducing drag by 20-30%. A 12-antenna controlled reception pattern antenna (CRPA) array bolsters resistance to electronic warfare jamming, ensuring reliable terminal guidance even in contested airspace. Released from high altitudes, the bomb rotates 180 degrees post-drop, deploying wings and igniting the engine for sustained propulsion, reaching speeds of 800-900 km/h. In operational terms, the FAB-3000-UMPK-PD has been combat-tested in eastern Ukraine since mid-2025, targeting deep rear-area logistics and command nodes. Its 1.4-ton explosive yield can level multi-story buildings or crater runways, while the standoff capability shields launch aircraft from ground fire. Production ramps up at facilities like the Izhevsk Mechanical Plant, with monthly outputs exceeding 500 units. However, challenges persist: the bomb's mass limits fuel efficiency, capping practical range at 150-180 kilometers under load, and vulnerability to advanced air defenses remains a concern. Nonetheless, this evolution underscores Russia's shift toward affordable, mass-produced precision munitions, blending Cold War brute force with 21st-century lethality.

💥 The Chinese authorities have known for 4 years that a pilot of a China Eastern Airlines jet — flight MU5735 — deliberately crashed the aircraft, killing all 132 aboard, according to data from the US. The data, released by the 🇺🇸 National Transportation Safety Board (NTSB), confirms earlier leaked US accounts that Flight 5735, a Boeing 737, was intentionally crashed into mountains in Guangxi in Mar 2022. The NTSB readings from the flight recorders show two pilots wrestling over the controls after both engines were shut down by hand, the automatic pilot was switched off and the jet was pushed into a nosedive as it cruised between Kunming and Guangzhou. In the face of public anger, Beijing has failed to publish a report. Last July the Chinese Civil Aviation Administration responded to an inquiry with a warning that “disclosure [about the crash] may, if released, endanger national security and social stability”. Beijing is under pressure from international aviation organizations to come clean over the disaster, which appears to have followed a similar pattern to suspected murder-suicide acts by airline pilots that have killed hundreds since 2014. The NTSB was asked to decode the flight recorders of Flight 5735 and transmitted its readings to China two weeks after their recovery in 2022. The US agency released extracts from its findings on Thursday in response to a Chinese citizen’s freedom of information request. “It was found that while cruising at 29,000ft, the fuel switches on both engines moved from the run position to the cut-off position,” the NTSB said. “Engine speeds decreased after the fuel switch movement.” Graphs of control inputs and the aircraft’s movement showed a pilot’s yoke pushing the aircraft into a steep dive and efforts by the other pilot to halt the dive. The two pilots were turning their yokes in opposite directions, commanding left or right rolls from the ailerons on the edges of the wings. The report said that a power failure had halted the data recorder after 90 seconds but the battery-powered crew voice recorder had continued. The agency did not reveal the contents, which it transmitted to Beijing at the time and said it had not stored a copy. Video from the ground showed the Boeing plunging vertically. The crew made no radio calls and no emergency radar code was transmitted. Previous Chinese reports have said that all systems appeared to have been functioning normally. Two months after the crash, a US investigator said “the plane did what it was told to do by someone in the cockpit”. China removed all references to that report, including screenshots, from social media. Three pilots were on the flight deck. Captain Yang Hongda, Zhang Zhengping, the first officer, and Ni Gongtao, a second officer in training. Speculation in China has centred on Zhang, one of the airline’s most experienced pilots, who had recently been demoted from his captain’s rank.

The US agency released extracts from its findings on Thursday in response to a Chinese citizen’s freedom of information request. “It was found that while cruising at 29,000ft, the fuel switches on both engines moved from the run position to the cut-off position,” the NTSB said. “Engine speeds decreased after the fuel switch movement.” Graphs of control inputs and the aircraft’s movement showed a pilot’s yoke pushing the aircraft into a steep dive and efforts by the other pilot to halt the dive. The two pilots were turning their yokes in opposite directions, commanding left or right rolls from the ailerons on the edges of the wings. The report said that a power failure had halted the data recorder after 90 seconds but the battery-powered crew voice recorder had continued. The agency did not reveal the contents, which it transmitted to Beijing at the time and said it had not stored a copy. Video from the ground showed the Boeing plunging vertically. The crew made no radio calls and no emergency radar code was transmitted. Previous Chinese reports have said that all systems appeared to have been functioning normally. Two months after the crash, a US investigator said “the plane did what it was told to do by someone in the cockpit”. China removed all references to that report, including screenshots, from social media. Three pilots were on the flight deck. Captain Yang Hongda, Zhang Zhengping, the first officer, and Ni Gongtao, a second officer in training. Speculation in China has centred on Zhang, one of the airline’s most experienced pilots, who had recently been demoted from his captain’s rank.
