Two members of the British Lothian and Borders traffic police were out on
the Berwickshire moors with a radar gun recently, happily engaged in
apprehending speeding motorists, when their equipment suddenly locked-up
completely with an unexpected reading of well over 300 mph.
The mystery was explained seconds later as a low flying Harrier hurtled
over their heads. The boys in blue, upset at the damage to their radar
gun, put in a complaint to the RAF, but were somewhat chastened when the RAF
pointed out that the damage might well have been more severe.
It seems that the Harrier's target-seeker had locked onto the 'enemy'
radar and triggered an automatic retaliatory air-to-surface missile attack.
Luckily, the Harrier was operating unarmed.
Otherwise... "Gee Officer, sorry about your patrol car........"
