SUPERFLIGHT

Major William Knight set a new world airspeed record flying an X-15 rocket plane at 4,534 mph, launched from a B-52 bomber. The plane's exterior reached 1,500 degrees due to air friction, requiring a special heat-dissipating material similar to space capsules. Despite this, the plane was scorched, and Major Knight noted it was hotter than expected. The video briefly mentions the London Motor Show.
