TCAS, yes the 757 was doing one of the student exchange flights I believe and parked on the old stand 10 I think. That was one of the 2 that had the stand centre line curving round to face back out at about 45degrees to the runway nose out. The IL76 was parked on the current 7 or 8 stand area looking at the photo I have of it. This was obviously quiet a few years ago so maybe they are more careful now about the stand weights!
