Stop letting your ego get in the way of your brain.
Yes yes yes… we know you are a fighter jock and probably look like Tom Cruise.
Cough, cough!
I'm sure BB could have said "single engine", "multi engine", "3 engine", "4 engine" or, "4 engine with APU", and most readers here would have understood his "big picture" point.
Please re-read, and in place of "multi engine", insert: "single engine, mach 2.3 MMO, mach 5 razor, ninja 900 riding, "she's lost that loving feeling" A-hole.
Does it make any sense now??
Good post BB!
Please bear in mind our C-172 jocks next time!
