Look, rather than flog this to death, what 'clip' are you talking about? Which airline/country/nationality/operator, because what you are insisting took place would not happen in any normal operation. It would not be a touch and go because the auto-spoilers operated. The only other option is some sort of contaminated runway to prevent flap damage from debris, but for a 747 it seems very unlikely. I have never heard of this, so let's have some details please!
