Factual error: The function of the US Navy in this movie in being called to raise an intact aircraft is plausible. Their actual role is usually to do with raising submarines. That being said, what isn't plausible is for a 747 to be heavy enough to cause equipment such as strapping to snap and fail, when a submarine is so many magnitudes heavier. A fully laden 747 can be over 400 tonnes, a moderate Los Angeles class submarine is over 6000 tonnes.

Factual error: Whilst the use of air-filled balloons is entirely credible when raising something like a 747, the air balloons would not lift the aircraft out of the water. The balloons would go as high as the ocean surface and no higher, meaning the access doors to escape the aircraft would still be submerged.
