banana head:
I thank you for your explanation. Perhaps you missed the inverted commas around "kick-off drift"? It is, as you say, a combination of the two.
What I was trying to impart is that you simply cannot touch down in a 747 with 10° of wing down like you can happily do in a DC-10 which is a truly wing-down technique aeroplane.
You cannot scrape a pod in a DC-10 - you get the wingtip first!
