The North American X-15 flew 199 missions to the edge of space, generating engineering data that still shapes modern aircraft and commercial spaceflight regulation.
The X-15 set the all-time air speed record of Mach 6.72 in 1967, and its thermal, control, and reentry data directly shaped Apollo, the Space Shuttle, and every hypersonic vehicle in development today.
The Stratolaunch Roc - with its 385-foot wingspan - is now actively flying hypersonic research missions, recovering test vehicles intact for the first time in decades.
Pancho Barnes broke speed records, organized Hollywood stunt pilots, and built the legendary bar where test pilots gathered after breaking the sound barrier.
