The LockMart F-35 Lightning II stealthy jet fighter seems to have a flaw: if it gets struck by lightning, its fuel tank could explode. This is a bad thing.
So the UK is grounding theirs. They are not allowed to fly if there is a thunderstorm anywhere nearby. However, I’m uncertain just how many the Raf has; it’s not due to enter service in Britain until 2018 or so, and they’ve only signed up to buy 48 of the now hideously expensive aircraft.
