To counteract shifts in gravitational pull , engineers build Typhoon on 'floating ' concrete rafts with laser trackers and computer-automated jacks . This £2.5 million system means the jet is accurately aligned . The aircraft can fly at speeds of up to Mach 3 - more than twice as fast as a Boeing 747 airliner flying from London to New York or Tokyo. And the Typhoon helmet lets pilots 'see ' through the bottom of the jet .
