Two Police Officers, checking for speeding motorists on the A1 Great North Road near Edinburgh, were surprised when their hand held device recorded a speed of over 300mph on a vehicle approaching on the crest of a hill. the device the stopped working. The radar had in fact locked on to a NATO Tornado fighter jet engaged in low-flying exercises over the North Sea. The chief constable fired off a stiff complaint to the RAF Liason office. The reply, in true laconic RAF style "thank you for your message, which allows us to complete the file on this incident. You may be interested to know that the tactical computer in the Tornado has automatically locked on to your "hostile radar equiptment" and sent a jamming signal back to it. Furthermore, the sidewinder air-to-ground missiles abourd the fully armed aircraft had also locked on to the target. Fortunately the Dutch pilot flying the Tornado responded to the missile status alert intelligently and was able to override the automatic protection system before the missile was launched."
