I have a problem and I am not sure of the explanation I came with.

Suppose there is a plane that is nosediving perpendicular to Earth. What will the "passengers" feel? In the first seconds the acceleration will be equal with the gravitational acceleration and they will feel wheightless much like in the reduced gravity aircrafts. But what happens after that? The plane will continue to accelerate. Let's ignore the fact that it will reach his terminal velocity for a second. In that period of time in which the plane will continue to accelerate steadily what will happent to the passengers? The constant acceleration will create the sensation of a gravity that acts towards the tail of the plane as stated by the equivalence principle or they will fall faster than the plane because of the lack of drag that the plane gets?

Thank you very much for your time!
