Its astonishing forward-swept wings were just one of its many bold innovations. Created at the height of the Cold War by a conglomerate of giants — NASA, the US Air Force, the “men in black” at the Defense Advanced Research Projects Agency (DARPA) and aerospace behemoth Grumman — it first flew in 1984 as part of a quest to build the ultimate fighter jet. But its highly experimental design made it the most aerodynamically unstable aircraft ever built. “It was unflyable — literally — without a digital flight computer on board, which made corrections to the flight path 40 times a second,” said Christian Gelzer, chief historian at the NASA Armstrong Flight Research Center in southern California (where the plane was tested) in a phone interview. “The engineers concluded that if all three flight computers had failed together, the airplane would have broken up around the pilot before the pilot had a chance to eject.” The Grumman X-29 had a wingspan of 27 feet and was 48 feet long. It could reach Mach… Read full this story
