Forget supersonic jets of the past, NASA’s X-43A hypersonic aircraft has already made short work of the old Guinness Book of Records’ fastest jet in the world. The new record will make its appearance in the 2006 Guinness World Records book.
The 3.6m-long scramjet achieved Mach 6.83 - nearly seven times the speed of sound - in a flight on 27 March. The record is set to be included in the 2006 Guinness World Records book. But the record may not stand for long, because another X-43A flight in October aims to smash it by flying to Mach 10 - 10 times the speed of sound.
