Why do you have to have 2 engines to have 3 bars?? Hell I get paid more than most of the turboprop regional captains despite having only 1 engine, i reckon I should be allowed to wear 3 bars if I feel like it!!
I do own a set of 3 bar eppaulettes but I dont wear them too often, usually just as a pisstake when I know im flying into an airport a mate woks at :-P
