Titre : D-558-I in flight

Description : (La description de cette image n'existe qu'en anglais)

The Douglas D-558-1 Skystreak is seen close-up in this early 1950s inflight photograph. Although less well known than the X-1, the D-558-1 could carry out research roles that complemented those of the more glamorous, rocket-powered craft. The D-558-1 was relatively slow, with only one flight exceeding a speed of Mach 1 (the speed of sound). However, the jet-powered Skystreak could fly for sustained periods at transonic speeds, increasing the amount of data a single flight could yield. By contrast, the rocket-powered X-1 could only provide transonic data for brief periods on each flight.
