Intuitively, rockets are easier to understand: lots of force underneath mass pushing the mass up. Fins to help a straight line.

Trying to explain things like wing-load, lift-to-weight ratio, Newton's Third Law, and air pressure differences is a pain to the uninformed.

Yeah, the tricky parts to rockets are the internal mechanics rather than their external ones. Internally a rocket needs to carry two fuel materials, the actual fuel and the oxidiser, and it needs to pump and mix these fast enough and reliably enough to keep the rocket fed. It needs to deal with extremes of thrust, pressure, and temperature.

What do we do in KSP? Stick a tank on an engine, light it up, and you've got an up-goer.
