Airport '77

A 747 jumbo jet crashes into the sea in the infamous Bermuda Triangle. Somehow the main body of the plane remains intact and the survivors have to face the grim reality of their situation. They are unable to communicate with the outside world, their air supply is limited and it cannot be long before the fuselage gives way under the pressure of the water. With the rescuers searching in the wrong part of the ocean the aircraft's occupants must find their own means of escape.
