The Convair 990 was a financial disaster that cost General Dynamics one of the largest corporate losses in history but thanks to some fascinating aerodynamics it was also the world’s fastest subsonic airliner.  This is the story of a little known airliner and the transonic design that allowed it to cruise at Mach 0.97!
