- A Bell Aircraft Corporation film document the Bell X-1A flights, starting with Chuck Yeager's 12 December 1953 flight up to 74,700 feet and culminating with Arthur Murray's flight up to 90,440 feet in 28 May 1954.
Original faded color was correct as best as possible, along with film dust removal, conversion to the original 24 fps frame rate and geometry correction.

The Bell X-1 (Bell Model 44) is a rocket engine-powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics-U.S. Army Air Forces-U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly 1,000 miles per hour (1,600 km/h; 870 kn) in 1948. A derivative of this same design, the Bell X-1A, having greater fuel capacity and hence longer rocket burning time, exceeded 1,600 miles per hour (2,600 km/h; 1,400 kn) in 1954. The X-1, piloted by Chuck Yeager, was the first manned airplane to exceed the speed of sound in level flight and was the first of the X-planes, a series of American experimental rocket planes (and non-rocket planes) designed for testing new technologies.
Ordered by the Air Force on 2 April 1948, the X-1A (serial number 48-1384) was intended to investigate aerodynamic phenomena at speeds greater than Mach 2 (681 m/s, 2,451 km/h) and altitudes greater than 90,000 ft (27 km), specifically emphasizing dynamic stability and air loads. Longer and heavier than the original X-1, with a stepped canopy for better vision, the X-1A was powered by the same Reaction Motors XLR-11 rocket engine. The aircraft first flew, unpowered, on 14 February 1953 at Edwards AFB, with the first powered flight on 21 February. Both flights were piloted by Bell test pilot Jean "Skip" Ziegler.
After NACA started its high-speed testing with the Douglas Skyrocket, culminating in Scott Crossfield achieving Mach 2.005 on 20 November 1953, the Air Force started a series of tests with the X-1A, which the test pilot of the series, Chuck Yeager, named "Operation NACA Weep". These culminated on 12 December 1953, when Yeager achieved an altitude of 74,700 feet (22,800 m) and a new airspeed record of Mach 2.44 (equal to 1620 mph, 724.5 m/s, 2608 km/h at that altitude). Unlike Crossfield in the Skyrocket, Yeager achieved that in level flight. Soon afterwards, the aircraft spun out of control, due to the then not yet understood phenomenon of inertia coupling. The X-1A dropped from maximum altitude to 25,000 feet (7,600 m), exposing the pilot to accelerations of as much as 8g, during which Yeager broke the canopy with his helmet before regaining control.
On 28 May 1954, Maj. Arthur W. Murray piloted the X-1A to a new record of 90,440 feet (27,570 m).
The aircraft was transferred to NACA during September 1954, and subsequently modified. The X-1A was lost on 8 August 1955, when, while being prepared for launch from the RB-50 mothership, an explosion ruptured the plane's liquid oxygen tank. With the help of crewmembers on the RB-50, test pilot Joseph A. Walker successfully extricated himself from the plane, which was then jettisoned. Exploding on impact with the desert floor, the X-1A became the first of many early X-planes that would be lost to explosions.

Interesting that they didn't mention Yeager's out of control tumble just after he'd managed Mach 2.5. However, if you watch the pilot getting on board the X-1A for the altitude flight, he's wearing some padding on top of his crash helmet. That's because Yeager cracked the canopy with his head during the gyrations on his flight.
They usually don't report negative events, but the footage is there. Sometimes out of context regarding the narration but it's there most of the times.
That’s the one where Chuck ‘uncorked it’, according to Jack Ridley.
Murray also tumbled after reaching the top of his 90K foot flight. You know what happened to Yeager in his infamous flight in the NF-104, where he flew with the nose up, but there was just enough atmosphere to keep him from getting the nose down with the reaction control rockets? Well, the X-1A was in the same situation, except it didn't even have the control jets. Murray could not get the nose down and he tumbled. The nose came down on its own when he fell to a lower altitude where the air was thicker and he was able to regain control.
Amazing times the 50s into the 60s.
Awesome history thanks! I met Yeager twice, once at Macdill AFB in 1988 and once at Lakeland Sun N Fun airshow, I forgot the year. He was something!
A really great find.
The detailed coverage of flight preparation was great.
Thanks as usual.
Great footage!
Amazing that they could make an unswept wing go through trans-sonic without disintegrating.
USA: Attempts to reach space via careful, incremental manned program using powered flight and specialized aircraft
USSR: Jams young test pilot into metal ball, lashes it to ICBM, fires it to space
USA: -Shrugs at the stunt and carries on with its aerospacecraft program-
wonder why they didn't bother installing an ejection seat on it ....
Took huge ones to do that.
Retro Space HD i am ready would you get me Apollo 11 Launch Please.
George Welch is just as important.
Good gawd... liquid alcohol and oxygen.
Criminal that these flight test guys weren’t allowed to be astronauts. Yeager should have been in charge of the astronauts corps.
Have you heard the joke about the two British astronauts that walk into a pub?
No
@@muppetrowlf1473 LOL! You just did!
Oh look…. A Miles M52 with a Bell badge on it.
Up the Brits!
Please stop spreading lies and ignorant misinformation about the Bell X1 program.
The British did not contribute any technical data used in the Bell X1 program.
The Miles M.52 never existed.
The M.52 never existed
Ooohhhh, yes it did. In every aspect apart from a full size aircraft.
Bell were given all the technical information including aerodynamic model testing.
Who do you think made the link between a rifle bullet and the aircraft shape? Miles Aircraft Limited.
@@muppetrowlf1473 The Miles M.52 is pure British science fiction... no aircraft by this name ever existed.
In hindsight we know that the M.52 would have never reached Mach 1.
Stop writing fiction.
Like all of the USA’s aerospace/rocket technology. It came from Europe.
