Why Do Helicopter Pilots Sit On the Right Hand Side?

Mystery Hour Question

I've noticed (from watching TV) that helicopter pilots sit on the right hand side, but airplane pilots sit on the left. Why is this?

Answer

Unlike airplanes, helicopters need constant steering and direction on the "cyclic" control stick to stay in the air.

Helicopters are designed so that the majority of people's dominant hand can easily rest on the stick at all times.
