Few years back three fighter jets had a dog fight over this area, now

Not sure if it still does, but a Tornado used to show at the British
Grand Prix at Silverstone. The near supersonic level flight in towards
the track, then the almost instantaneous transition to vertical,
followed by it climbing at an amazing rate to almost out-of-sight was
awe inspiring and deafening. It was so loud that car alarms across the
car parks went off in unison!
