Early 90's two fast pointy things (probably Tornados) over flew the Marconi building in Milton Keynes. So low that they set off car alarms all around.
The building was part of the Foxhunter radar design / development group (or so I was told). The flyby was totally unoffical and no-one got the tail numbers (yer right). However the presence of most of the company on the roof made the council take a very dim view of the event. <img src="wink.gif" border="0">
