ver Cuevana 3. A plane crashes in the Pacific Ocean six minutes after takeoff, and is flooded after an explosion during evacuation. A dozen survivors sink in a sealed part of the aircraft as it perches precariously on an undersea cliff 200 feet below the surface. Among them is an engineer and his 11-year old daughter. Based on the book Drowning: The Rescue of Flight 1421 by T.J. Newman
