Why airplanes fly

Yeah, it was a Miles aircraft. The M-52
They got as far as a mockup but dropped the project. It had a
stabiliator and the brits are fond of whining that it was that
development on the X! that enabled it to break the sound barrier.
However, this was not a Brit innovation. As usual, the germans had
realised that in the thirtie, years before Miles..

Intersting -- do you know what aircraft the Germans used that on? If
you have a book reference (or web) on that I'd like to read about it.

Sometimes it blows my mind how many advances were made in the
thirties. The ME 109, Spitfire, and P-38 all come out of that time.
Plus a host of others I probably know nothing about.
