Joy Ride:
I didn't ignore the british efforts but only concentrate on the first mach-1 flights to describe how long the development from the ME262 had to be before the soundbarrier was defeated!
And I do know that among the tricks the americans had to use to achieve the record was the all-tail flipping of the Miles!
The P51 is only mentioned because of it's participation in the painting!
Beside I think that the P-38 have been the prop-driven plane of WW2 wich came closest to the sound-barrier :-/
