Errrrrrrr....
Helicopter=H, Aeroplane=A
Rotors, hovering, V max approx 150KIAS, can't fly across atlantic, crap weather, poor pay, fun flying.....
Wings, quick, long range, comfy, boring to fly when up to speed, pay better......
Hope that helps!
p.s. Slightly different machines to fly, something to do with bumble bees and aerodynamics
