water from an over flow in the galley, mmmm. I have been a QF engineer on line for a few years and we are constantly unblocking drains that have been filled with coffee grinds and all kinds of junk.
Maybe, hopefully the lazy flight attendents (not all) will learn how much they can jeopardise the aircraft and think while they work!
As for some earlier threads, The QF 747-400 APU can't operate in flight at all. Yes it is designed to but QF does not have the inlet Door mod to do so. Besides, 4 generators didn't die, so whats the point of putting 2 more down the back on in a situation like this.
I have seen water in lift shaft many times, mainly comes from upperdeck door area and galley. that part of A/C is too far back to get to the MEC as the nose up pitch will not allow it.
