that two cops with a speed gun on an overpass over the A9 in NE Scotland (near RAF Lossiemouth) are stood scratching their heads at their speedgun, as it read 700mph

they looked up & down the road at the traffic- none of which was going anything like that speed

story go`s that around a thousand feet above them, an RAF Tornado pilot was frantically shutting down his automated firing systems that figured an anti aircraft weapon had locked on!
I hope that`s a true story, the thought of Brimstone missiles hitting that overpass in those circumstances is hysterical (in theory guys- in theory)
