15.08.1957 odbył się 24 lot X-1B z Neilem Armstrongiem, pilotem testowym NACA.

On his first X-1B flight (#24, NACA flight #14), OTD in 1957, NACA research pilot Neil Armstrong completes a pilot familiarisation mission. Upon landing the X-1B's nose gear fails resulting in minor damage. Armstrong flew the next X-1B mission in November of that year.

12.12.1953 Chuck Yeager w Bell X-1A  osiągnął wysokość  22769 m i prędkość 2604 km/h (2,44 Mach).
Oznaczało to ustanowienie nowego rekordu prędkości.
https://www.thisdayinaviation.com/12-december-1953/
Był to 10. lot X-1A (48-1384), jedynego egzemplarza samolotu rakietowego o takiej nazwie, który wykonał 26. lotów z udziałem 4. pilotów.
Była to wersja rozwojowa X-1 (XS-1).

70 years ago today, Chuck Yeager piloted Bell X-1A to Mach 2.44, a new record for piloted aircraft at the time. After reaching Mach 2.44, the X-1A tumbled out of control, twice reaching 8 Gs. Yeager recovered from inverted spin and landed the aircraft.

Podczas tego lotu napotkał sprzężenie bezwładnościowe.
X1-A dokonał lotu wokół wszystkich trzech osi, spadając na wysokość ponad 40 000 stóp, zanim powrócił do normalnego lotu.

12 December 1953. Chuck Yeager in the Bell X-1A achieved an altitude of 74,700 feet and a new air speed record of Mach 2.44. During this flight he encountered inertia coupling. The X1-A tumbled about all three axis as it fell more than 40,000 feet before recovering level flight.

70ème anniversaire du 10ème vol du X-1A avec @GenChuckYeager .Il atteint Mach 2,44. A mach 2,3, l'avion devient instable et alors qu'il est en subsonique et à 15 250 mètres, l'avion part en vrille inversée... qu'il récupère à 7 625 mètres.

05.01.1949 Charles „Chuck” Yeager samolotem Bell X-1 wykonał jedyny konwencjonalny start (z pasa startowego) podczas programu X-1, osiągając wysokość ok. 7010 m w 90 sekund.

5 January 1949. Charles "Chuck" Yeager, using a Bell X-1, carried out the only conventional (runway) take off performed during the X-1 program, reaching 23,000 ft. in 90 seconds.

The only conventional runway launched flight of the X-1 was performed by Yeager OTD in 1949, the 104th flight in the programme. Piloting #46-062 with a reduced 50% fuel load, he attained 7,000 m (23,000ft) and Mach 1.03 in 90 seconds.

Chuck Yeager piloted Bell X-1 in the only ground takeoff of the X-1 program #OTD in 1949.
Originally designed for conventional ground takeoffs, safety and performance concerns prompted mission planners to air-launch X-1 aircraft from Boeing B-29 or B-50 Superfortresses.
