Hypersonic jet ready for launch
`A new jet engine design able to fly seven times the speed of sound is scheduled to launch over Australia on Saturday.
The scramjet engine, known as Hyshot III, has been designed by British defence firm QinetiQ.
If successful, it could pave the way for ultrafast, intercontinental air travel, and substantially cut the cost of putting small payloads into space.
The engine will launch on a rocket owned by the University of Queensland.’
