Comment on why do pendulums and space shuttles feel the effects of earth rotation but airplanes do not?

They are two different things: the space shuttle gets a boost of speed from the speed of the rotating earth, while the pendulum is undergoing precession.
The difference between airplanes and the spacecraft is that airplanes move through a ‘static’ atmosphere with friction which just leaves them moving point A to B. Whereas spacecraft are accelerating into space, into virtually no friction, so having that speed of the earth to start off with is a bonus.
The pendulum only gets friction in the same direction of it’s swing, however the earth’s rotation introduces the precession. The frictional forces on an airplane are mad and everywhere on the plane, with the plane constantly adjusting so precession would have no effect on its path.
