Explore the incredible engineering, history, and records of the legendary North American X-15 rocket plane! Welcome to The X-15: The Fastest Plane Ever Built Could Never Take Off. In this 12-minute documentary from Hidden Systems, we dive deep into the remarkable story of the X-15 program—from air-launching off the wing of a B-52 mother ship and pushing past Mach 6.7 to reach speeds unmatched by any crewed powered airplane to this day, to flying to the edge of space at over 67 miles high. Discover the pilots like Pete Knight, Joe Walker, and Neil Armstrong, the challenges of hypersonic thermal stress, and the legacy that shaped modern aerospace and spaceflight!
