Re: ww2 airplane geek? ever wondered about mach 1 w props?
That's a little harsh. The fuselage of the X-1 was designed after an object of which it was well known that it could fly stable at supersonic speed: the cal .50 machine gun bullet. Ans it wasn't quite like in the movie*. Yeager did fly with broken ribs that day, but it was by no means his first spin in the X-1. They practically inched their way forward - every filght just a little faster, a little modifacation on the controls here, a little modification at the engine there, and so on. Yeager's autobiography gives a good account. He was a pilot's pilot, he took risks, but he was smart enough to know when to stop. Well worth a read, other parts of his life and career are even more amazing. (Yes, I'm a fan.)
That being said, the first pilot to break the sound barrier should have been Geoffrey de Havilland Junior. The de Havilland D.H.108 Swallow was a much more advanced plane than the X-1, but such is life.
* The Right Stuff, of course. If you watch it: Yeager has a cameo in Pancho Barnes'** bar. Watch out for "Fred".
** Also a larger-than-life-someone-should-make-a-movie-about-her character.
As to the Messerschmitts: there are stories that the odd Me 262 did go supersonic by accident in a steep dive, but we'll never know.
