The main gear looks just a few feet off the tarmac, so it must have passed VERY close to the guy bending over behind the fence. He must have come very close to being decapitated or the 747 was descending very steeply for an almighty touchdown- I would guess he's evacuating his digestive system bending over like that! Still having trouble visualising this- the guy is under the APU, yet the wheels are about to hit the under-run area. Even after 18 years flying 747s, I could never judge it this fine. Definitley an interview in the Flight Managers' Office!
