The Boulton Paul P.111, was Britain's tiny experimental delta-wing jet built right after WWII to unlock the secrets of tailless deltas. Powered by a Rolls-Royce Nene turbojet, it first flew on October 10, 1950, with detachable wingtips for quick tests between blunt and pointed shapes — one of the...

NEWS: SpaceX has released a statement after today's successful 11th Starship test flight. "Every major objective of the flight test was achieved, providing valuable data as we prepare the next generation of Starship and Super Heavy. The flight test began with Super Heavy igniting all 33 Raptor engines and ascending over the Gulf. The successful first-stage ascent was followed by a hot-staging maneuver, with Starship’s upper stage igniting its six Raptor engines to continue its flight to space. Following stage separation, the Super Heavy booster completed its boostback burn to put it on a course to a pre-planned splashdown zone off the coast of Texas using 12 of the 13 planned engines. Under the same angle of attack tested on the previous flight, the booster descended until successfully igniting all 13 planned engines (including one that did not relight during the boostback burn) for the high-thrust portion of the landing burn. The booster successfully executed a unique landing burn planned for use on the next generation booster. Super Heavy hovered above the water before shutting down its engines and splashing down. After completing a full-duration ascent burn, Starship achieved its planned velocity and trajectory. During flight, Starship successfully deployed eight Starlink simulators and executed the third in-space relight of a Raptor engine, demonstrating a critical capability for future deorbit burns. Starship re-entered the Earth’s atmosphere and was able to gather extensive data on the performance of its heatshield as it was intentionally stressed to test the limits of the vehicle’s capabilities. In the final minutes of flight, Starship performed a dynamic banking maneuver to mimic the trajectory that future missions returning to Starbase will fly. Starship then guided itself using its four flaps to the pre-planned splashdown zone in the Indian Ocean, successfully executing a landing flip, landing burn, and soft splashdown. Focus now turns to the next generation of Starship and Super Heavy, with multiple vehicles currently in active build and preparing for tests. This next iteration will be used for the first Starship orbital flights, operational payload missions, propellant transfer, and more as we iterate to a fully and rapidly reusable vehicle with service to Earth orbit, the Moon, Mars, and beyond."

The best-preserved warship in the world is also one of the most catastrophic failures in naval history. It sank on its maiden voyage, after sailing barely 1300 meters, in front of thousands of horrified spectators... It is called the Vasa, and it was meant to be the most magnificent warship ever built. Constructed between 1626 and 1628 on the orders of King Gustavus Adolphus of Sweden, it bristled with 64 bronze cannons and was covered, from bow to stern, in hundreds of gilded and painted sculptures of lions, warriors, and mythological figures, all designed to announce the power of the Swedish crown. It was a floating palace built for war. On the 10th of August 1628, the Vasa set sail from Stockholm harbour on a calm day with a light breeze. The gun ports were open, the cannons run out to fire a ceremonial salute. A first gust of wind heeled the ship over, and it slowly righted itself. Then a second gust struck. The ship leaned hard to one side, water poured in through the open lower gun ports, and within minutes the pride of the Swedish navy rolled over and sank, less than a mile from where it had begun. Around 30 people died, in full view of the crowds who had gathered to watch it depart. But the disaster became a miracle: the Vasa sank into the cold, oxygen-poor, low-salt water of the Baltic Sea, where the shipworm that devours wooden wrecks in most of the world's oceans cannot survive. So the ship did not rot. It waited... For 333 years it lay on the harbor floor, almost perfectly intact, until it was raised in 1961. Today, more than 95 percent of what you see is the original seventeenth-century timber. It is the only preserved ship of its century anywhere on Earth. The thing that should have erased the Vasa from history is the very thing that saved it. Had it sailed successfully, it would have served its years, worn out, and been broken up for scrap centuries ago, like every other warship of its time. Because it failed so completely, and so quickly, it survived. We can stand before it now, an extraordinary relic of the seventeenth century frozen in time, only because, on its very first day, everything went wrong... If this kind of history fascinates you, I send out a piece like this every week to readers who love finding the extraordinary stories the past left behind.

sorry, they just did WHAT someone gave a machine one disease name, the leading cause of blindness in the developed world with 1.5 million americans already in its path, and it came back pointing at a drug that has sat in pharmacies for years under a different label: 551 papers read in 30 minutes against the 294 hours a human would have needed, and the loop that did it is public on GitHub most agent setups answer one question at a time, so the ceiling on the work is the quality of the question you happened to think of this one was handed a single question and wrote the second one itself. turns out that follow-up is where the real find was: a target called ABCA1, upregulated threefold, in an experiment no human ordered i read the whole paper looking for the trick, and the trick is structural. that is the second question, and it is the gap between an assistant and a factory: - hand the loop a field rather than a task: it was given a disease, and choosing the mechanism was part of its job - make it rank before it spends: 151 papers in, ten candidate mechanisms out, scored against each other before anything touched a bench - split reading from judging, so the agent that forms the theory is a different agent from the one grading it - close every cycle on physical reality: the verdict was an experiment, and another model's opinion was never allowed to stand in for one - feed each result back as the next question rather than a log line, which is the step almost nobody builds - search what already passed inspection first: the winner was an approved compound with a safety file already on record - write down what the round learned before opening the next one, so round two starts where round one stopped my read, and i think it is the uncomfortable one: reading was the entire bottleneck in that field, and everybody spent the decade optimising the writing. people ran every physical experiment here, the analysis agent needs a domain expert writing its prompts, and the authors decline to call this the leap it resembles. the thinking got replaced, and the hands did not so the question i cannot answer for my own setup: which step of your loop still stops dead until you sit down and type something bookmark this one. the four parts that turn one model into a line that runs like this, the queue, the rooms, the write permissions and the gate, are built file by file in the piece below ↓

The Airbus A350 is, without question, the most beautiful airliner gracing the skies today. A masterpiece of modern engineering and design, it combines elegance with efficiency. From every angle, the A350 is perfectly proportioned. Its long, graceful fuselage flows seamlessly into a set of gently curved wings that flex in flight like a bird in motion—an iconic silhouette that instantly sets it apart. The wingtips, with their signature upturned ‘sharklets,’ don’t just look stunning—they whisper of aerodynamic excellence and fuel-saving innovation. Its nose profile is distinctive yet refined, with a gentle curvature and a cockpit visor that gives the aircraft a futuristic, almost predatory presence. And unlike many other widebodies, the A350’s fuselage length is in perfect harmony with its wing span and tail height—there’s a visual symmetry that makes it appear poised, balanced, and utterly graceful, whether taxiing on the tarmac or soaring above the clouds. But it’s not just a pretty face. The A350 is a triumph of technology—built from over 50% carbon-fibre-reinforced composite, powered by next-generation Rolls-Royce Trent XWB engines, and brimming with advanced systems that make it one of the most efficient and capable long-haul aircraft ever built. In an age where function often overrides form, the A350 is a rare exception—a true flying work of art that proves beauty and brains can coexist. 📸 by ig/captainchris Not an ad

Today I had my first demo drive in a Tesla. It was also my first time ever sitting in one. This was the first car I’ve ever sat in the driver’s seat of where I didn’t touch the steering wheel for over 20 miles. Before I even got to the car, the people who had demoed it before me were an older married couple who were absolutely euphoric. They thought it was so cool that the car could drive itself. The Tesla employee told me this happens all the time. People come back from demo drives and tell the next test driver that they’re about to have an amazing experience. Little did I know, I’d end up carrying on the torch to the next couple demoing it after me. There was a ton of construction where I demoed the car, and FSD handled the entire drive extremely well. And yes, it can go through a drive-thru and stop at each window. The only thing I had to do was tap the pedal because it wouldn’t leave on its own, but it was still wild seeing the AI stop perfectly at the second window and wait. There are a million things I could write about why a Tesla feels like a better car and how much more it offers compared to a regular car. But for now, I’ll stick to FSD. There were only two moments that made me a little uneasy. The first was pretty minor. The car slightly hesitated going up a driveway, but quickly made up its mind. The second was more noticeable. I didn’t realize the car was nagging me. Once I touched the steering wheel, nothing happened, so I pulled it right a little harder, then let go. After that, the car turned left and crossed a double yellow on a backroad. (and yes I know you can sue the volume knob) I’m not totally sure if it was trying to pull over or what it was doing. I wanted to see how it would handle the situation, but there were cars coming, so I took over and corrected it. One of the coolest moments was when I thought FSD was glitching because it came to a complete stop in the middle of a busy road. Then I looked around and realized why. On the right side, there was a bicyclist waiting at a yellow crosswalk. The cars behind me didn’t honk, and the Tesla stopping actually incentivized another car in the right lane to stop and let him pass. The car is almost too nice to pedestrians, because 99.999% of humans would’ve blown through that, especially with no flashing light. For 99.9% of the drive, the car navigated confidently and smoothly. It was a real “feel the AGI” moment. Please do not let the media, the general public, or anyone else convince you that this technology is just some kind of auto assist or glorified cruise control. This is undoubtedly getting extremely close to feeling superhuman. You still have to pay attention to the road, but after experiencing it myself, I’d be shocked if HW4 Teslas aren’t unsupervised within the next couple years. The car was extremely smooth. There was no harsh braking, and it even avoided something in the road that I didn’t see. Driving with FSD made me realize I probably wasn’t driving as well as I could be. Hopefully, eventually, everyone’s car can be as mindful as a Tesla. I’ve never seen a brand so far removed from the public’s sentiment. I’m so happy I ordered one.

The past year has seen me have a renaissance, in the truest sense… I won’t go into details now but will at some point before long. What has brought so much happiness to my life and those around me this past year has been my falling back in love with sport. Cycling has, and always will be, my number one. Yet I’d forgotten that I simply love sport, not for results but for the sheer joy of doing it, I’d completely forgotten that the health of my mind is intrinsically connected to the health of my body. I’ve rediscovered the love I had for sport that existed before the world of professional cycling took over in the way it did. I’ve been pushing myself and trying new things this past year, indifferent to the results, just out having fun and at times going deeper than I thought I was capable of anymore. Last week I got on a TT bike for the first time in a decade, Factor Bikes built me a bike, I’ve been looking at it for two years and decided it was time to get fitted, getting back on it felt like going home. Anyway, the long and the short of this is that it’s inspired me to create a club to inspire and be inspired. A community for us to share our love for getting out there and doing it, because I’ve realized that although I spend most of my sporting life on my own I derive the most pleasure when feeling part of something. It’s in its early days, I’ve called it Sporting Club CHPT3 aka SCC3, I’d love you to check it out and join. It’s still in its infancy, but I hope it’s going to grow into something that will inspire you as much as me.

USAAF 14th PRS Spitfire PR Mk XI gunned down at point blank range likely by a Luftwaffe Me 262 jet fighter in 1944 The incident pictured most likely involved Spitfire PR Mk XI PL782 flown by 2nd Lt Robert B Hilborn. The aircraft was intercepted over Lechfeld by Leutnant Alfred Schreiber of Erprobungskommando 262 in Me262 A-1a WerkNr. 110372 "White 3". This latter unit was the first to deploy the Messerschmitt jet and would later form Kommando Nowotny. Hilborn managed to bail out of his stricken aircraft and was taken prisoner. The USAAF insignia on the top of the port wing is clearly visible as the aircraft banks away and both the severe vibration on firing and size of the cannon shell impacts suggest 30mm gunfire consistent with the Me 262's MK 108 battery in the nose, and the jet aircraft would also have been able to comfortably keep up with the fast unarmed photoreconnaissance Spitfire variant at altitude. The 3cm Minengeschoss high-capacity shells were formidable projectiles each containing over 70 grams of high explosive and were designed to detonate within six or so inches of having penetrated the aircraft skin, destroying the aircraft structure in the process and rendering the aircraft unflyable after only a few hits. The amount of debris flying off the Spitfire after only three visible detonations is testament to the devastating effect of such fire. The US 14th Photographic Reconnaissance Squadron began to train with British-made Supermarine Spitfire Mk V fighters in July 1943 before equipping with the photographic reconnaissance PR Mk XI variant later that year. The squadron flew combat reconnaissance missions in the European Theater of Operations from August 12th 1943 until April 25th 1945. The squadron's Spitfires flew the majority of the target photography missions, including the first Spitfire reconnaissance mission over Berlin in March 1944, while the other squadrons of the 7th Photographic Group (Reconnaissance) equipped with F-5 Lightnings concentrated on photographic mapping. Deep penetration missions included reconnaissance of oil refineries to determine when repairs had been performed that could justify returning them to Eighth Air Force's target list. The Squadron earned a Distinguished Unit Citation for reconnaissance missions flown over France between May 31st 1944 and the end of June. The squadron flew over 300 successful sorties to support Operation Overlord, the invasion of Normandy. It flew missions over the Netherlands to support Operation Market Garden in October 1944 and conducted damage assessment of Germany until July 23rd 1945. In late 1944, the Spitfires, flying solo missions and relying only on speed and altitude for defense, began to prove vulnerable to the jet powered Messerschmitt Me 262 fighters entering service with the Luftwaffe. A squadron aircraft lost on September 5th 1944 was probably the first Army Air Forces loss to a German jet fighter. Erprobungskommando 262 had been formed in April 1944 at Lechfeld just south of Augsburg, as a test unit (Jäger Erprobungskommando Thierfelder, commanded by Hauptmann Werner Thierfelder) to introduce the Me 262 into service and train a corps of pilots to fly it. This was not Leutnant Schreiber's first go at an Allied reconnaissance plane, while flying over Munich on July 26th he encountered a Mosquito PR Mark XVI of No. 540 Squadron RAF piloted by Fl. Lt. A.E. Wall. Schreiber attempted to shoot down the unarmed Mosquito, though Wall evaded Schreiber's three attack runs and was able land safely at Fermo in Italy after what was the first air to air interception by a jet fighter in history.
