What is this movie?

[pjalne]

I once saw an airplane movie where there was a terrorist on the plane and there was a fight between him and the hero which ended with a gun going off and breaking a window so there was a pressure problem. And then there was another fight later which resulted in the bad guy falling off the plane and the hero saying something snappy as the bad guy fell (don't remember what exactly). Then the hero's love interest had to land the plane even if she only knew how to control miniplanes and never got around to learning how to take off or land (both pilots were dead).
