Newton's laws of motion.

Consider an airplane taking off. You can feel yourself being pushed back into your seat, so you are experiencing a force (that is not gravity). However, you remain at rest w.r.t. the coordinate system fixed to the airplane. So the first law of Newton seems to fail: we are at rest, so there is no acceleration and yet a force is exerted on us. When the airplane is traveling at a constant speed on a constant height, however, we feel no force (except for gravity) and the first law seems OK again. HOW IS THIS POSSIBLE???
