Oh trust me, I only knew it was a 747, coz I'd been watching it for a while. Visually, we were in front of the 747 on a parallel track, and an airprox/tcas event would have been next had we turned. So if you are suggesting that I turn in front of a huge lump of metal that I can see just because my clearance is something else then I need to say, gulp, airmanship?
