I seem to remember being told the Jag on the Motorway stunt, it was the only stretch straight and long enough without bridges to allow it to do it, the bombs were fibreglass dummies too to make it look good, but to keep the weight down.. I can see why they did it with a Jag, as it wouldn't trigger any speed camera
Now if you want to talk runways used as motorways USAF Burtonwoods main runway was used as part of the M62
