I was an ATCA at Heathrow about a million years ago, and was standing at the bus stop one evening, looking across the road to the CTB, when I spotted the boss (Basil Turner) coming out through the doors. As this happened, there was an ear splitting roar and a PIA 707, on an overshoot seemed to miss the top of the tower by not much at all. The thing that impressed me was that the boss didn`t break stride at all; just did a very smooth 180 turn back into the building.
