NASA’s experimental X-59 aircraft has flown faster than the speed of sound for the first time, marking a significant step in the development of quiet supersonic flight technology.
NASA test pilot Jim "Clue" Less took off and landed at Edwards Air Force Base in California, reaching a top speed of approximately Mach 1.1 (1,147 km/h) and an altitude of 13,228 metres.
The aeroplane’s flight began at 11:08 am local time (8:08 pm CEST) on Friday and lasted 81 minutes. The engineering team focused on flying qualities at both subsonic and then supersonic speeds.
