Well of course, having searched high and low, I can't lay my hands on the video! However, having watched it - and the Super 8 movie - on numerous occasions, there is a B17 of some description duffing up the tower.
What has come to light is the whole week's recording of 'Airport 86' introduced by Mike Smith and Sarah Greene from LHR. This is from a time when 757s were the latest thing, BA had still not been privatised, Swanwick wasn't even a distant gleam, and Ms Greene had the mandatory big shoulder pads and 'explosion in a candyfloss factory' perm of that era!
