Simonflyer, if you don't know something, it is prudent to keep quiet rather than open your mouth and be seen to be a fool
Go easy on the guy, he's in Australia. The aircraft fly upside down there so when they look as if they're on climb out they're actually landing and vice versa. And when the 'wheels' look as if they're down, they're really up. Flaps are reversed too. Jeez, I wonder how those pilots who fly between Europe and Australia cope with all that stuff. Do the cabin service carts run along the aircraft ceiling?
