On a lighter note, some years ago over East Anglia, a very flat area on the Eastcoast of England, a Belgian F16 pilot on lowlevel livefire exersise got quite a shock when his treath warning went off, and his missile locked on to a radar which had locked on to him. Realising that the likelyhood of a sam site was remote, he overrode the system and didn't fire a missile.
Which was lucky for the policeman who was tracking him with his speed radar gun, as he had mistaken the low aircraft for a speeding car on the horizon.......
