Well Dexter I may only be a humble GA pilot but there's no need to get supercilious, I'm just reporting what I saw.
The wings were indeed noticeably bowed upwards as I imagine all 747's tend to be when they're full up. One of the air ambulance boys took a couple photos of it on short finals, I'll see if I can get him to post them perhaps.
Secondly, one would have to check the calibration of the VASIs but assuming they're set for 747 pilot eye height then they're supposed to be 47 or 48' crossing the threshold, I have spent enough time sitting about on the C1 apron to have a vague idea what that looks like from outside, and to me they were maybe 30 or 40' higher than they should have been at the threshold, they touched down maybe a couple of hundred yards past A3 which would confirm that supposition.
I don't see anything in that posting that renders me an 'armchair expert' but feel free to flame away at me if you wish
