The US military's F-35 Joint Strike Fighter aircraft is proving to be a pain in the neck in more ways than one.
Not only did the Pentagon spend almost $400 (£238bn) billion to buy 2,400 aircraft (about twice as much as it cost to put a man on the moon), the F-35 programme is seven years behind schedule and $163 billion (£97bn) over budget. This at a time when cuts in the defence budget are forcing the Pentagon to shrink the size of the military.
