Hmmm.. reminds me of a fly-by at Heathrow some tome ago. A DC-9 with a gear problem asked to fly-by so we could take a look.. He came across 28L (yes - old controller here!) threshold and turned straight for the tower. He passed us absolutely level with the windows which meant he crossed T2 with feet to spare. I kid you not - people outside T2 threw themselves on the ground. It was brilliant!!!
