A Wing and a Prayer

Ever notice how the wings on a jet can often look like they're in pretty bad shape? Fact is, jets don't need wings at all. They are held aloft by their eponymous turbojets, much like the space shuttle, which is why the wings don't flap except in emergencies. They are only there so that people on the ground do not mistake them for Incoming Bomb Missiles (ICBMs).

Prop planes, on the other hand, need wings to keep them from spinning in the opposite direction of their propellers. Just like a helicopter!
