US Navy Pilots Test Captured Japanese Fighters (1945) 🇺🇸🇯🇵 Colorized footage captures U.S. Navy pilots conducting flight trials with a captured Nakajima Ki-43 Hayabusa credited with 16 aerial victories and a Mitsubishi A6M Zero credited with 11 victories near the Navy’s Patuxent River testing grounds in Maryland in June 1945. By flying and evaluating these aircraft firsthand, Allied pilots gained valuable insight into their strengths and weaknesses, helping them develop tactics that exploited superior speed and diving performance while avoiding the turning battles where Japanese fighters excelled. A fascinating look at how the Allies studied the enemy to gain an advantage in the air war over the Pacific.

MH17: Worst airliner shootdown in history was 12 years ago July 17 2014: Malaysia Airlines Flight MH17, a B-777, is shot down over Hirabve (Ukraine). All 298 aboard die. A criminal inquiry stated the jet was hit by a SAM missile fired from an area controlled by Pro-Russian Rebels. The investigation was led by the Dutch authorities – over two-thirds of the passengers were from that country - who concluded that the missile system was traced to a Russian brigade that later returned to the country in the aftermath, as confirmed by earlier independent enquiries. In 2018, the Netherlands and Australia held Russia responsible and initiated legal action, while Russia denied involvement. In November 2022, a Dutch court convicted two Russians and one Ukrainian separatist of murdering all 298 people on board, stating Russia had control over the separatist forces. MH17 was Malaysia Airlines’ second loss in 2014 – after the disappearance of MH370 in March - and remains the deadliest aircraft shoot-down in history.

🚨I visited the Israel-Gaza Border w/ the Last Mayor of Gaza (FULL DOC): We stood where Hamas launched its attacks. We saw the, the destruction, and the aftermath of October 7th. And the mayor breaks down the money trail to expose who profits from war and who is funding the war. This documentary breaks down: 🔹 How Hamas operates and funds itself 💰 🔹 The brutal history of Israel and Gaza 🔹 What life was like before and after Hamas took over in Gaza 🔹 Why Israel responded the way it did 🔹 The Iron Dome’s failure and how Israel failed to defend themselves on October 7 🔹 The Nova Music Festival massacre—what really happened? This is the most intense investigation I’ve ever done and has been shadow banned on platforms like Youtube. You won’t see this video from the MSM.

The first 747 brought down by lithium batteries September 3 2010: UPS Flight 6, a cargo B-747, crashes in Dubai (UAE); both pilots die. Crew reported fire aboard after take-off and were unable to return to the airport. The conflagration was caused by “autoignition” of a cargo pallet, which contained over 81,000 lithium batteries. The conflagration triggered an intense, uncontained fire that quickly compromised the aircraft's critical flight systems. It filled the cockpit with dense smoke, blinding the crew and burning through the captain's emergency oxygen supply, which caused him to lose consciousness. Despite heroic efforts by the First Officer to fly the crippled jet alone with guidance from air traffic control. Unable to see his instruments or guide the plane to the runway, he crashed into a military base near Silicon Oasis. In the aftermath of this accident and a similar occurrence with an Asiana 747 in July 2011, international regulators started enacting stricter laws for shipping hazardous electronics. It also mandated the use of fire-resistant cargo containers and improved cockpit emergency oxygen systems to help pilots survive catastrophic smoke. In a sad coincidence, the accident occurred near the anniversary of another major tragedy caused by an onboard fire – Swissair 111 had crashed on September 2nd 1998. Video is from the Mayday ACI series episode on the occurrence, named “Deadly Delivery”

The reality after acquittal for Karen Read did not mean instead relief. 😩 Immediately after she was found not guilty of the murder of her Boston Police officer boyfriend John O'Keefe, she had a wave of emotions and doubt. The trial gave her purpose and when it ended, that purpose vanished. No job. No home. No routine. A void in both body and mind. PTSD doesn’t disappear just because a verdict does. She describes grief turning into anger, appetite and energy gone, cortisol and stress catching up after years of survival mode. Sometimes she forgets it’s over. Sometimes thoughts appear and she still thinks she needs to tell her mom things "just in case." She’s still healing. Finally reacting to years of persecution she had to swallow just to survive. She lived in fight-or-flight, worked under extreme pressure (which she said she is good at), and swept emotions aside to keep going. Now she’s digesting and understanding what the government has actually done. The freedom is real.. but so is the aftermath. ❤️

Advertorial pages are crushing it for e-comm and affiliate. And I just automated the entire creation process with AI 🤯 Product URL → AI research → full pre-sale page draft in minutes. All inside n8n + Airtable. Perfect for e-comm brands and affiliates who know these pages convert but hate building them from scratch. Here's the problem: You know you should be testing listicles and pre-sale pages. Ridge does it. HexClad does it. Javi Coffee does it. But every page takes hours. Researching the product, writing the hook, structuring the sections. It's a huge pain in the a$$. This system solves it: → Submit product URL + customer avatar via Airtable form → FireCrawl scrapes the entire product page → AI generates components: core problem, failed alternatives, unique mechanism, benefits, social proof, trust signals → Review and edit each section before final generation → Click one button to generate the full advertorial page No starting from a blank doc. No watching competitor videos manually. No rewriting the same sections over and over. What you get: - Three formula templates (transformation story, problem-solution listicle, premium brand listicle) - Editable component fields so you can tweak before final output - Full markdown page ready for your team to polish - Extensible structure to add your own formulas Built 100% in n8n + Airtable + FireCrawl. I recorded a full walkthrough showing exactly how this works and how I built it AND I'm including the n8n template. Want the full tutorial + n8n workflow? >Like this post > Comment "LIST" And I'll send it over (must be following so I can DM)

This UFC fighter is called Themba Gorimbo. His mother died when he was 9 and his father died when he was 13. When he was 16-years-old he traveled to the local fields to illegally dig for Marange diamonds. Even though it was illegal, it was the only work he had and eventually when police found him, they had German shepherds bite him. "If you see my body, l've got dog marks all over my body where I was bitten by the dogs.” "That night probably changed me mentally as a person, changed everything because I got bitten by the dogs and I lost a lot of blood and I almost died. Luckily, I survived and I'm here to tell a story about it." Recently, he won his first fight in the UFC and up until that point he only had $7 in his bank account. All his money was spent on the flight to Vegas. He sleeps on a couch in his gym. After his fight, he sold his fight gear for $7000 and used the money to build a water pump in Zimbabwe. What a pure soul ❤️

Do you know what an exoplanet is? 2019 physics laureates Michel Mayor and Didier Queloz have explored our home galaxy, the Milky Way, looking for unknown worlds. In 1995, they made the very first discovery of a planet outside our solar system, an exoplanet, orbiting a solar-type star called 51 Pegasi. They reported their discovery in a Nature article, published in November 1995. This discovery started a revolution in astronomy and over 4,000 exoplanets have since been found in the Milky Way. See the original article: Video animation: Animation of a exoplanet. The exoplanet HD 189733b lies so near its star that it completes an orbit every 2.2 days. In late 2011, NASA's Hubble Space Telescope found that the planet's upper atmosphere was streaming away at speeds exceeding 300,000 mph. Just before the Hubble observation, NASA's Swift detected the star blasting out a strong X-ray flare, one powerful enough to blow away part of the planet's atmosphere.

We are excited to share our work “Event-Aided Sharp Radiance Field Reconstruction for Fast-Flying Drones” published in IEEE Transactions on Robotics IEEE Transactions on Robotics (T-RO), which tackles sharp radiance field reconstruction under agile drone motion, where RGB frames are heavily motion-blurred and pose priors become unreliable! 4 years in the making! Code & dataset released! PDF: Code & Dataset: Full Narrated Video: High-speed flight is essential for time- and battery-constrained missions (e.g., inspection, exploration, search & rescue). However, fast motion corrupts visual data with severe motion blur and introduces drift/noise in visual-inertial odometry, making NeRF-based 3D reconstruction particularly brittle. We propose a unified framework that leverages asynchronous #EventCamera streams together with motion-blurred frames to reconstruct high-fidelity radiance fields from agile drone flights. Our key idea is to embed event-image fusion directly into radiance field optimization while jointly refining a shared, continuous-time camera trajectory initialized from event-based VIO. This enables us to recover sharp radiance fields and accurate trajectories without ground-truth supervision during training. We validate our method on synthetic data and on real sequences captured by a drone flying up to 2 m/s. Despite severe blur and noisy pose priors, our method preserves fine scene details and achieves a performance gain of over 50% on real-world data compared to state-of-the-art methods.

🇺🇸🇮🇷🇮🇱 - US-Iran Air Campaign (Feb 15 – Apr 16) Over the last 2 months, Rerum Novarum has tracked 7,642 publicly available US military flights in support of Operation Epic Fury. Involving over 572 unique aircraft, marking the largest US air power buildup since Operation Iraqi Freedom in 2003. Over the course of the 60-day air campaign, 1,601 transatlantic crossings were made, averaging just over 26 transatlantic flights per day. 195 unique cargo aircraft made 1335 flights across the Atlantic, and 182 unique aerial refueling aircraft made over 228 flights across the Atlantic; over 80% of these aircraft made a 1 way trip across, inferring they stayed within the CENTCOM/EUCOM AOR to support the operation. The US Military currently fields roughly 475 aerial refuelers, meaning almost 40% of the military's refueler aircraft were used to support Operation Epic Fury. Many of these refuelers were likely towing attack aircraft into the region, which we cannot track. In the two weeks leading up to the operation (Feb 14→28), 1191 flights were made into Europe and the Middle East, with an average of 85 flights per day. Since the first day of the war, 28th of February, the US Military has maintained an average of 141 military flights per day within the CENTCOM/EUCOM AOR, with the busiest week being March 14→21, with 1262 flights, and an average of 180 flights per day. The most active aircraft type during this operation was; C-17 (Cargo): 3399 Flights. KC-135 (Aerial Refueler): 2703 Flights. C-130 (Small Cargo): 850 Flights KC-46 (Aerial Refueler): 217 Flights C-5M (Large Cargo): 185 Flights These cargo aircraft (C-5s, C-17s, and C-130s) flights combined have a theoretical maximum uplift capacity of 651,385,985 lb (295,555 metric tons), or about 1,427,000 cubic metres of cargo space. The attached video shows the full 60 day air campaign of all publicly available flights. This data only includes public flight data; military aircraft can, and do, turn off their public ADSB transmitter whenever they want to, therefor flights such as B-52's or fighter jets rarely show themselves on public data except for special cases which makes them hard to track. Although aircraft used for cargo or refueling generally fly with this data publicly accessible in safer areas,meaning the overwhelming majority of these support flights were captured.

The Reckless Couriers: Packages Flying Like Fallen Stars In the quiet suburbs where porch lights flickered like distant hopes, a new breed of modern-day wanderers roamed the streets in their rumbling vans—delivery drivers on a mission that seemed more like a chaotic game of dodgeball than a service of care. They called themselves couriers, but to the watchful eyes behind curtained windows, they were storm-bringers, hurling boxes and envelopes through the air with the casual flair of a pitcher in the ninth inning. One fateful afternoon in a sleepy Texas neighborhood, young Sarah peered out her window as another brown truck screeched to a halt. The driver, sweat-streaked and hurried, grabbed a fragile package marked “Handle with Care” and launched it toward her doorstep like a discus thrower at the Olympics. It tumbled end over end, landing with a sickening thud against the welcome mat. Another followed—a heavy box that bounced once, twice, before spilling its secrets across the lawn. Packages flew everywhere that day: over fences, into bushes, skidding across driveways like runaway meteors. Some drivers dropped them with a shrug, others tossed them with surprising athleticism, turning routine deliveries into spectacles of airborne absurdity. Word spread like wildfire through the community. “Did you see the one who drop-kicked the Amazon box?” neighbors whispered. “Or the guy who yeeted my new blender clear across the porch?” What began as frustration bloomed into legend. These weren’t just careless workers; they were anti-heroes in a fast-paced world that demanded speed over gentleness, quotas over caution. Their vans became chariots of commerce, but their throws told a deeper tale—of exhausted souls racing against the clock, of a system that valued velocity above all. Yet in the quiet aftermath, as families gathered their battered goods and shook their heads in disbelief, one truth lingered: in the age of instant everything, even the simplest deliveries had become a wild, unpredictable story of flight and fall. And somewhere out there, another driver was revving his engine, package in hand, ready to write the next chapter.

Magnetohydrodynamic (MHD) Propulsion - What Is It?" by AsteronX #ufotwitter This video, titled "Magnetohydrodynamic (MHD) Propulsion - What Is It?" by AsteronX, explains the physics, operating principles, and potential applications of magnetohydrodynamic field propulsion for aerospace and spaceflight. 1. What is MHD Propulsion? [00:15] Magnetohydrodynamics (MHD) is the study of electrically conductive fluids—such as ionized gases, plasmas, or saltwater—interacting with magnetic fields [01:04]. MHD propulsion uses electromagnetic forces to accelerate conductive fluids directly, producing thrust without moving mechanical parts like propellers, turbines, or airfoils [02:29]. 2. Physical Mechanism: The Lorentz Force [02:47] Working Principle: When an electric current passes through a conductive fluid perpendicular to an applied magnetic field, it generates a perpendicular Lorentz Force [02:47]. Pressure & Acceleration: This magnetic force directly accelerates or decelerates the fluid particles, driving fluid flow and creating thrust or pressure gradients [08:30]. 3. Atmospheric Flight Mechanics [10:03] Air Ionization: Since neutral atmospheric air is non-conductive, the aircraft must ionize incoming air into a conductive sheath, often using high-frequency (radio/microwave) pulse discharges [10:19]. Aerodynamic Integration: The accelerated ionized air can be directed over specialized airfoils—such as saucer-shaped Coandă effect structures—to generate lift dynamically across the body [11:27]. 4. Space Application Concepts [12:20] Plasma Rocket Engines: Utilizing magnetic fields and Lorentz forces to accelerate cold or superheated plasma out of a nozzle without physical grid erosion [12:31]. Quantum Vacuum Thrusters (Theoretical): The video discusses futuristic concepts using ultra-short, intense electromagnetic pulses to interact directly with quantum vacuum virtual electron-positron fluctuations [13:35]. The core concept in the presenter's design is hull-integrated disc vehicle geometry, rather than an internal thruster, linear duct, or traditional rocket nozzle. In the video, AsteronX emphasizes that for magnetohydrodynamics (MHD) to be practical in atmospheric flight, the vehicle's physical shape and propulsion system must be unified into a single structure. Key Architectural Features of the Disc/Saucer Design 360° Coandă Effect Airfoil: Instead of pushing air through an internal engine tube, the saucer geometry acts as a continuous "wing wrapped around the vehicle". Plasma or ionized air accelerated across the curved upper skin adheres to the surface via the Coandă effect, generating low pressure and continuous lift across the entire hull. Surface Boundary Layer Sheath: High-frequency pulse discharge electrodes embedded along the outer skin ionize ambient air into a conductive plasma sheath surrounding the disc. The Lorentz force directly manipulates this sheath, eliminating aerodynamic drag, shockwaves, and thermal heating during flight. Field Drive vs. Mechanical Thruster: Rather than using discrete thruster pods or jet exhausts, magnetic and electric field arrays distributed across the disc's surface manipulate the fluid directly in 360 degrees, allowing omnidirectional maneuvering without moving parts or control surfaces. (This geometry directly builds on historical field-acceleration concepts, such as Jean-Pierre Petit’s MHD aerodyne and saucer research cited in the video description).

Magnetohydrodynamic (MHD) Propulsion - What Is It?" by AsteronX #ufotwitter This video, titled "Magnetohydrodynamic (MHD) Propulsion - What Is It?" by AsteronX, explains the physics, operating principles, and potential applications of magnetohydrodynamic field propulsion for aerospace and spaceflight. 1. What is MHD Propulsion? [00:15] Magnetohydrodynamics (MHD) is the study of electrically conductive fluids—such as ionized gases, plasmas, or saltwater—interacting with magnetic fields [01:04]. MHD propulsion uses electromagnetic forces to accelerate conductive fluids directly, producing thrust without moving mechanical parts like propellers, turbines, or airfoils [02:29]. 2. Physical Mechanism: The Lorentz Force [02:47] Working Principle: When an electric current passes through a conductive fluid perpendicular to an applied magnetic field, it generates a perpendicular Lorentz Force [02:47]. Pressure & Acceleration: This magnetic force directly accelerates or decelerates the fluid particles, driving fluid flow and creating thrust or pressure gradients [08:30]. 3. Atmospheric Flight Mechanics [10:03] Air Ionization: Since neutral atmospheric air is non-conductive, the aircraft must ionize incoming air into a conductive sheath, often using high-frequency (radio/microwave) pulse discharges [10:19]. Aerodynamic Integration: The accelerated ionized air can be directed over specialized airfoils—such as saucer-shaped Coandă effect structures—to generate lift dynamically across the body [11:27]. 4. Space Application Concepts [12:20] Plasma Rocket Engines: Utilizing magnetic fields and Lorentz forces to accelerate cold or superheated plasma out of a nozzle without physical grid erosion [12:31]. Quantum Vacuum Thrusters (Theoretical): The video discusses futuristic concepts using ultra-short, intense electromagnetic pulses to interact directly with quantum vacuum virtual electron-positron fluctuations [13:35]. The core concept in the presenter's design is hull-integrated disc vehicle geometry, rather than an internal thruster, linear duct, or traditional rocket nozzle. In the video, AsteronX emphasizes that for magnetohydrodynamics (MHD) to be practical in atmospheric flight, the vehicle's physical shape and propulsion system must be unified into a single structure. Key Architectural Features of the Disc/Saucer Design 360° Coandă Effect Airfoil: Instead of pushing air through an internal engine tube, the saucer geometry acts as a continuous "wing wrapped around the vehicle". Plasma or ionized air accelerated across the curved upper skin adheres to the surface via the Coandă effect, generating low pressure and continuous lift across the entire hull. Surface Boundary Layer Sheath: High-frequency pulse discharge electrodes embedded along the outer skin ionize ambient air into a conductive plasma sheath surrounding the disc. The Lorentz force directly manipulates this sheath, eliminating aerodynamic drag, shockwaves, and thermal heating during flight. Field Drive vs. Mechanical Thruster: Rather than using discrete thruster pods or jet exhausts, magnetic and electric field arrays distributed across the disc's surface manipulate the fluid directly in 360 degrees, allowing omnidirectional maneuvering without moving parts or control surfaces.

Another ill-fated take-off over V1 (in this case, V2!) June 13 1996: Garuda Indonesia Flight 865, a DC-10, crashes in Fukuoka (Japan) 3 of 275 aboard die. On take-off, the jet had just left the ground when one of the engines failed. Crew opted to reject the maneuver; the aircraft was unable to stop safely and left the runway: landing gear collapsed, and the airplane caught fire. Inquiry noted pilot actions by aborting takeoff above V1, where SOP dictated pilots should have continued takeoff and deal with the engine later. More info below from Aviation Safety Network – Aftermath video is from Aircrashdaily (go give them a follow on YouTube) “The DC-10 accelerated for takeoff. The nose was raised, and at a speed of 158 kts, the first officer called "Rotate". It was 12:07:40. Three seconds later, at a radio altitude of 9 feet, a fan blade of the 1st stage HP turbine from the no. 3 engine separated. The N1 dropped to 23,7% within a few seconds. At 12:07:45, the flight engineer called "Engine failure number one." Takeoff was aborted at about the V2 speed, and the airplane contacted the runway one second later at a vertical acceleration force of 2.1 Gs. The thrust reversers were deployed and ground spoilers were extended. The DC-10 skidded off the runway through a ditch, fence and a road, before coming to a halt 620 m past the runway threshold. Investigation revealed that the turbine blade that failed, had operated for 30913 hours and 6182 cycles. General Electric had advised customers to discard blades after about 6000 cycles. Accident cause Although the Aircraft was well in excess of V1 and the aircraft had already lifted off from the runway, the takeoff was aborted. Consequently, the aircraft departed the end of the runway, came to rest and caught fire. It is estimated that contributing to the rejection of the takeoff under this circumstance was the fact that the CAP's judgement in the event of the engine failure was inadequate."

🧵 Evasive Maneuvers In the aftermath of the USS Trembling Puppy acknowledging the loss of yet another fighter aircraft in the midst of a Yemeni missile attack, many speculations have arisen regarding what actually happened. The "official" story is that an F/A-18 and its tow tractor were flung overboard while performing "evasive maneuvers" in the face of oncoming Yemeni anti-ship cruise missiles. Many are skeptical of the "official" story of the jet going overboard as a result of an evasive maneuver. Some think a US carrier would not even attempt an "evasive maneuver" to elude a cruise missile. But US carriers are trained on such maneuvers, even though I suspect they have limited potential efficacy. Some think the Yemeni may have used loitering drones to shoot down an F/A-18 on landing approach to the carrier. This is an interesting conjecture, and while I do not dismiss it outright, I consider it less likely than the "official story". Let's first consider the anti-ship cruise missiles, which are either Iranian "hand-me-downs", or at least based on legacy Iranian designs, with a range up to 2000 km, a speed of ~.7 Mach, and a ~250 kg warhead. From a launch point in Yemen, it would require over an hour of flight time to travel the 1000+ km distance to the carrier strike group in the northern Red Sea. It must be assumed that US surveillance assets are able to track such missile launches along their entire path, and so CSG-8 should have been continuously apprised of the position of the various components of the strike package. In other words, Rear Adm. Sean R. Bailey, commander of Carrier Strike Group Eight, and Captain Christopher "Chowdah" Hill, commander of the USS Harry S. Truman (CVN-75), both should have had real-time intelligence at every moment for 4+ hours of drone flight time, and over an hour of cruise missile flight time. That said, the MQ-9 Reaper drone is one of the integral components of US persistent surveillance capability — and as has been widely reported, the Yemeni have now shot down 22 of them, several in the last month alone. So it is altogether possible that US surveillance of these missile launches could be meaningfully impaired. At any rate, I figure the Yemeni are firing cruise missiles which, at best, have about a 250m circular error probability at a distance of 1000+ km. Even a salvo of a dozen would struggle to score a hit on a moving ship 1000 km away — and the Yemeni have typically only fired 2 or 3 in any given salvo. But apparently at least one got through the perimeter air defenses and the combat air patrol on this particular occasion, and was on a threatening track towards the Trembling Puppy. Therefore Captain Soggy Cookie veered in a panic, dumping an F/A-18 and its tow tractor into the sea, and splashing salty seawater into the still-open wound of the Trembling Puppy's February 2025 collision with a cargo ship just north of the Suez Canal. Anyway, no matter the as-yet-uncertain details, it's clearly another indisputable embarrassment for the US Navy, which has sought in vain for a year and a half to break the Yemeni selective blockade of the Red Sea. With the recent addition of the USS Timid Vinny (CVN-70), which is cowering somewhere in the calm blue waters of the northern Arabian Sea, the Yemeni have now put the fear of Allah into five separate US Navy carrier strike groups over the course of the past eighteen months. Alas, as I have long observed, there are #NoEasyWarsLeftToFight. In any case, this simple fact remains: against all odds and prior expectations, the chronically underestimated Yemeni remain the gatekeepers of the Bab-el-Mandeb, and are inflicting upon the United States Navy one of the most decisive strategic defeats in its heavily mythologized history.
