At the end of the film Jo breaks the door with the axe, causing the cabin to decompress, sucking her out, and then we see the jet shortly crashing into the Ocean. Also we here a news report stating "Government officials are reporting that a private jet has crashed into the sea off the coast of Norway. It seems the jet was flying EXTREMELY low, when the cabin de-pressurized" however, the cabin pressure would not be sufficiently different (if even different at all) to the outside air pressure, when flying at a low altitude.
