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.

Plot hole: The crash as presented in the movie is beyond preposterous. The tail fin striking the ocean surface would have torn it off. Even if we pretend the tail fin would be strong enough, the aircraft would catapult onto its nose and break up, meaning no survivors.

Continuity mistake: When the Captain is rescued by the Navy Zodiac, there are two Navy guys, one with a T-shirt on, the other bare-chested. When they get back to their ship, both Navy guys now have T-shirts on.
