However, the date of Welch's achievement was given as 26 April 1948 with no mention made of his earlier flights.”

CANADA AVIATION MUSEUM AIRCRAFT CANADAIR F-86 SABRE MK.6. [2004. július 28-i dátummal az eredetiből archiválva]. (Hozzáférés: 2006. november 23.) „The maximum speed listed at 606 mph (975 km/h) is in level flight, however, the SABRE could exceed the speed of sound (760 mph [1,224 km/h] at sea level and 660 mph [1,061 km/h] at 36,000 ft). This was accomplished by flying to an altitude of approximately 45,000 ft (13,720 m) and with full power applied accelerating to the maximum level flight speed. The aircraft would then be rolled to inverted flight and pulled down until it was pointing straight down at the ground at full power and allowed to accelerate until it was supersonic (Mach 1). Minor buffeting would occur and supersonic flight would be momentarily achieved at approximately 35,000 ft (10,670 m).”

(Hozzáférés: 2006. november 23.) „In a series of carefully controlled flight tests conducted in World War II by Messerschmitt, it was established that the Me 262 was out of control in a dive at Mach 0.86, and that higher Mach numbers would lead to a nose-down trim that could not be counter-acted by the pilot. The resulting steepening of the dive would lead to even higher speeds and self-destruction of the airframe due to excessive negative G loads. Postwar testing by the British government confirmed Messerschmidt's results.”
