No, I stick with my original answer. I don't cheat. I said LANDING. (But I know its wrong.) I don't get what you mean about asking a friend for an answer that knows the difference between a DC-10 and a B-747. 3 engines (dc-10) versus 4 engines, of two per wing B-747 verses an engine on the tail for the DC-10, versus the upper deck for the 747....who or what to ask? Kind of a no brainer.
