Advertisements Flying Supersonic My TiVo had recorded this as a suggestion. Apparently, it’s a new ep and it looks like you can watch it online. Was a bit surprising that they claimed the crash of the Soviet Tu-144 (aka Concordski) during an air show had an unknown cause. I'd seen another documentary (likely on PBS) MANY years ago claiming it was some other plane trying to take pictures who got too close (IIRC), surprised the Tu-144 pilot and caused them to overstress the Tu-144 in trying to avoid a collision, causing it to break up. Also, they didn’t touch on the retrofits made to the Concorde after its only crash when a piece of metal caused a tire to explode and fuel to leak. Prior to this, I knew virtually 0 about the backstory of the proposed Boeing 2707, a supersonic competitor and that JFK had announced an American effort to have a commercially viable supersonic passenger plane.
