Another post-war marvel. The 1946 Lockheed R6V Constitution (XR6O-1) was the largest fixed-wing aircraft ever operated by the US Navy it had a 189-ft wingspan and a double-decker pressurized fuselage. Only two prototypes flew. It was also tested with six JATO rockets mounted in the wing roots—shortened takeoff run...

Two air forces started the Pacific war. One trained its pilots, then kept them fighting until they died. The other trained its pilots, then often pulled many of its experienced combat pilots out to teach everyone else. This is one of the reasons America won the Pacific air war, let's dive in.. Japan's Elite Aviators At the start of the war, Japan had some of the finest fighter pilots in the world. The aviators who attacked Pearl Harbor were elite. Many had hundreds of hours in the cockpit and real combat experience from the fighting in China. Flying the nimble A6M Zero, they cut through Allied opposition in the early months of the war and earned a fearsome reputation. But Japan made a fateful choice about these men. It kept them in combat, more or less indefinitely. Japanese pilots flew mission after mission with no real system to rotate them home. They fought until they were shot down, crippled, or killed. It seemed ruthless and efficient. In reality, it was a slow-motion disaster. The Difference in Philosophy Because every time Japan lost one of those veterans, everything he knew died with him. America did the opposite. It regularly rotated many of its experienced combat pilots back home once they had done their share of fighting. There, they became instructors, pouring everything they had learned in real air combat directly into the next generation of pilots. So the two systems pulled in opposite directions. Japan's pool of skill drained away with every ace it buried. America's pool of skill grew, as each returning veteran multiplied his knowledge across hundreds of students. One nation was teaching. The other was simply dying. The Training Gap The gap became a chasm, and it was made worse by sheer scale. By 1944, the United States was training around 8,000 new aviators every month, each of them getting well over a year of instruction and hundreds of hours in the air before they ever saw combat. Japan could not come close. As its veterans vanished, its training program collapsed, and it was crippled by something else, too. Fuel. Japan was running so short of it that many trainees could barely fly enough hours to learn their trade. By the later part of the war, Japanese pilots were being rushed into battle with barely 100 hours of flying time, and sometimes far less. They were teenagers with almost no training, being sent up against American veterans who had been taught by the best combat pilots in the fleet. The outcome was no longer a contest. It was a slaughter. The Great Marianas Turkey Shoot Nowhere was that clearer than in the skies over the Mariana Islands in June 1944. When the Japanese launched hundreds of aircraft against the American fleet, they flew into a wall of Hellcat fighters, guided by radar and expert fighter direction that positioned the Americans at the perfect height and moment to strike. The green Japanese pilots in their now outdated Zeros never had a chance. In and around that battle, Japan lost nearly 480 aircraft, while the Americans lost only a few dozen. It was so one-sided that the American aviators nicknamed it the Great Marianas Turkey Shoot. Japan's naval air power, once the terror of the Pacific, was broken in a matter of days. Better Aircraft, Better Technology It was not only the pilots. It was the machines too. America kept producing better and better aircraft, like the tough, heavily armed F6F Hellcat, designed after studying a captured Zero and built to beat it. It could take punishment, out-dive and out-gun its opponent, and it was forgiving enough that even a less experienced pilot could survive his first fights and become a veteran. Over the war, Hellcat pilots claimed more than 5,000 enemy aircraft for a tiny fraction of that in losses. Japan, meanwhile, kept sending men up in the aging Zero, a plane that had been revolutionary in 1941 but was now underpowered, fragile, and outclassed. It was fast and agile, but a single burst of American fire could tear it apart, because it had traded armor and protection for maneuverability. Better pilots, in better planes, backed by better technology. The advantages stacked on top of one another. The Spiral Ends By the end, Japan had reached the final, desperate stage of the spiral. With almost no trained pilots left, and no way to make more in time, it turned to the kamikaze. A pilot did not need 500 hours of training to crash his aircraft into a ship. He only needed to take off, aim, and die. It was the last resort of an air force that had run out of the one thing it could never mass produce. Experienced men. America won the Pacific air war for many reasons. Its factories out-built the enemy. Its radar and intelligence gave it eyes the Japanese lacked. Its aircraft grew deadlier every year. But underneath all of it was something simpler. America treated its best pilots as a resource to be protected and passed on. Japan treated them as fuel to be burned. One of those choices built an air force that kept getting stronger. The other burned brightly, and then burned out. This was why America won the Pacific air war. I post a story like this every single day. Most people never see them. Follow so you don't miss the next one.

49 years ago today: America´s worst air disaster May 25 1979: American Airlines Flight 191, a DC-10, crashes on takeoff from O'Hare (Chicago, US). All 271 aboard plus 2 on the ground die, the deadliest airliner crash in US, a figure only surpassed by the 9/11 terrorist attacks. On take-off, the engine separated from the wing due to improper maintenance, damaging hydraulics, and causing loss of control, as detailed below. Specifically, it was determined that during takeoff rotation, the No. 1 (left) engine separated from the left wing, flipped over the wing, and landed on the runway. The separation severed the hydraulic lines that lock the leading-edge slats in place and damaged a 3-foot (1 m) section of the left wing’s leading edge. Aerodynamic forces then caused an uncommanded retraction of the outboard slats. As the aircraft climbed, the damaged left wing generated substantially less lift than the right wing, whose slats remained deployed, and the engine provided full takeoff thrust. The resulting aerodynamic imbalance produced an abrupt left roll to a 112° bank angle—partially inverted—before the aircraft crashed in an open field adjacent to a trailer park near the runway’s end. The engine separation was caused by structural damage to the pylon, resulting from improper maintenance procedures at American Airlines, which are detailed in the thread below 1/6 ⬇️ 🧵 Video – Plane N´ Boom (animation from Mayday ACI series)

(WARNING: content may disturb viewers) On This day: in 2005 Mandala Airlines Flight 091, a Boeing 737, crashes in Sumatra (Indonesia). Seconds after taking off from Polonia Int, Airport. The jet stalled and went down in a heavily populated area. 103 of 111 aboard are killed, along with another 47 on the ground die. The crash deeply shocked the people of North Sumatra, as Governor Rizal Nurdin and his predecessor, Raja Inal Siregar, were among those on board. Both were killed in the accident. Inquirty determined that the crew failed to configure the flaps and slats for take-off, pointing out a breach of SOP. It was also noted that the takeoff-configuration warning was not heard, which might also have failed, robbing the crew of another way to see their mistake. Video is AP Footage of the crash aftermath Other accidents from September 5 1999: Necon Air Flight 128, a BAe 748, crashes in Kathmandu (Nepal), all 15 aboard die. On approach to Tribhuvan airport, aircraft hit a 100 ft high communications tower and went down 9 mi from runway. Poor visibility (namely fog) was apparently a factor. 1954: KLM Flight 633, a Constellation, crashes off Shannon (Ireland) 28 of 56 aboard die. Plane impacted sea shortly after takeoff. Cause: crew actions, namely misinterpretation of instruments and inadvertent landing gear re-extension causing loss of climb performance. 1958: Loide Flight 652, a C-46, crashes in Paraíba (Brazil), 13 of 18 aboard die. On 3rd approach attempt in bad weather, plane hit ground in CFIT. Inquiry noted pilot actions, namely breach of SOP during the maneuver. Incorrect meteorological forecast was also a factor. Among the survivors was famous Brazilian Comedian Renato Aragão, then a young law student. 1946: a TLA DC-3 [“NC57850”] crashes in Nevada (US). 20 of 21 aboard die. On approach in dense fog, plane hit ground 2.4 mi from runway. Cause: crew continuing maneuver after losing visual contact with airport. Pilot unfamiliarity with terrain was also a factor. Flight (a charter) was operated by TLA – Trans Luxury Airlines 1945: a RAF C-47 [Registration “KN532”] crashes in Myingyan (Myanmar). All 31 aboard die. Enroute in a medevac flight, flight entered a monsoon thunderstorm. Shortly after plane had control issues, which caused the port wing to detach from aircraft. Aircraft was operated by No.48 Squadron 1945: a RAF C-47 [Registration “KP235”] crashes in Istres (France). 17 of 24 aboard die. On take-off run at night and in poor weather conditions, aircraft stalled out of control and hit ground near airfield. Aircraft was to start a transport mission to the Middle East.

Random Information Post ❗️ The F-15 S/MTD, part Ace Combat 7: Skies Unknown 's Experimental Aircraft Series Set DLC or available on it's own in the F-15 S/MTD Set DLC, is a semi-historical fictional aircraft. It is based on the real life F-15 STOL/MTD and later F-15 ACTIVE test aircraft. The aircraft used for the project was pre-production TF-15A (F-15B) No. 1 (USAF S/N 71-0290), the first two-seat F-15 Eagle built by McDonnell Douglas (out of 2 prototypes), the sixth F-15 off the assembly line, and was the oldest F-15 flying up to its retirement. The programs ran from September 7th 1988 to January 30th 2009, where the air frame was finally retired. The aircraft was used in several tests and experiments centered around thrust vectoring and advanced avionics equipment. the F-15 STOL/MTD program was intended to give F-15s the ability to take off from short or damaged runways in the event that a war with the Soviet Union damaged them or forced the use of sub-optimal backup airfields. The canards on the aircraft are stabilizers from an F/A-18 that were attached to the fuselage, removing the 20mm Vulcan cannon in the process to allow for the modification. The aircraft used two types of thruster nozzles, the first being a square 2D nozzle, allowing thrust vectoring up and down, and later a 3D nozzle allowing thrust to be vectored in all directions. The program showed good results, though not intended as a performance upgrade McDonnel Douglas engineers noted a 15% increase in the plane's overall dog fighting performance from the modifications. Also noting takeoff speeds as low as 42 mph (68 km/h), and a 25% reduction in the required runway length for takeoff. However the US Air Force did not buy these upgrades. No official reason was made public but the collapse of the Soviet Union in 1991 likely eliminated the need and enthusiasm to upgrade the fleet of F-15s. The test aircraft continued to serve on loan to NASA until 2008 however, and is now on display at Edwards AFB. Still a very cool aircraft to look at, and a common sight in Ace Combat games since Ace Combat 3, with it's fictional F-15S/MT Eagle+ variant being it's first appearance in the franchise, and is one of my favorite fictional aircraft in the series.
