Higher Further Faster | Evolution Of Aviation Part 1
A look at the evolution of aviation.
A Look at the X-15, SR-71, YF-12, X-43A and X-51.
The story of North American X-15 hypersonic rocket aircraft, reaching a top speed of Mach 6.70 and a staggering height of 67.1 mi (335.000 ft / 108 km). Learn about the courageous pilots that flew it and a brief history of rocket planes, including the Bell X-1, piloted by Chuck Yeager, the first to break the sound barrier, or the Bell X-2 that flew at Mach 3. The X-15 first flight was in mid 1959, more than 60 years ago. It also includes a series of vintage documentaries on the subject.
The X-15 set speed and altitude records in the 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour (7,274 km/h; 2,021 m/s), was achieved on 3 October 1967, when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet (31,120 m), or 19.34 miles. This set the official world record for the highest speed ever recorded by a crewed, powered aircraft, which remains unbroken.
During the X-15 program, 12 pilots flew a combined 199 flights. Of these, 8 pilots flew a combined 13 flights which met the Air Force spaceflight criterion by exceeding the altitude of 50 miles (80 km), thus qualifying these pilots as being astronauts; of those 13 flights, two (flown by the same civilian pilot) met the FAI definition (100 kilometres (62 mi)) of outer space. The 5 Air Force pilots qualified for military astronaut wings immediately, while the 3 civilian pilots were eventually awarded NASA astronaut wings in 2005, 35 years after the last X-15 flight.
The X-15 was based on a concept study from Walter Dornberger for the National Advisory Committee for Aeronautics (NACA) for a hypersonic research aircraft. The requests for proposal (RFPs) were published on 30 December 1954 for the airframe and on 4 February 1955 for the rocket engine. The X-15 was built by two manufacturers: North American Aviation was contracted for the airframe in November 1955, and Reaction Motors was contracted for building the engines in 1956.
Like many X-series aircraft, the X-15 was designed to be carried aloft and drop launched from under the wing of a B-52 mother ship. Air Force NB-52A, "The High and Mighty One" (serial 52-0003), and NB-52B, "The Challenger" (serial 52-0008, a.k.a. Balls 8) served as carrier planes for all X-15 flights. Release of the X-15 from NB-52A took place at an altitude of about 8.5 miles (13.7 km) and a speed of about 500 miles per hour (805 km/h). The X-15 fuselage was long and cylindrical, with rear fairings that flattened its appearance, and thick, dorsal and ventral wedge-fin stabilizers. Parts of the fuselage (the outer skin) were heat-resistant nickel alloy (Inconel-X 750). The retractable landing gear comprised a nose-wheel carriage and two rear skids. The skids did not extend beyond the ventral fin, which required the pilot to jettison the lower fin just before landing. The lower fin was recovered by parachute.

I've never hit "save" as fast while watching this. This is going to be epic! I already can't wait for Part 2. Bravo 👏

My Grandfather was one of the Bomber motherships. His ship was "The High And Mighty One". My Grandfather used to flip the X-15 the finger just before launching the wing cargo allowing the X-15 to fly away!

I had a YF12 model kit (Revell) around 1970. I read that the turning circle was something like Texas in reality so if it missed it lost the target.

2 comments in 2hr bro fell off
I really enjoyed this video tho BTW

FYI the black bird leaked fuel big time while on the ground on purpose since when it got up to speed all its components would expand and seal every thing up. Orings and such.

[@ioanbota9397]

Realy I like this powerful higher fastest planes

[@8kigana]

Mach 6.5 (5000 mph)? You are an astronaut in my book.

[@sylent_viper]

Some of the pilots received astronaut wings if they flew high enough

[@dmor6696]

we need to improve the materials to be able to endure the aerodynamic friction challenge
otherwise we're screwed
