Continuity mistake: Near the end of the film, when the SEALs are in the inflatable boats heading towards the coast of Beirut, there is a shot from behind showing all the SEALs wearing black diving suits. But when the shot changes to a close up of their faces, you can see they are wearing camouflage fatigues, not diving suits.
Continuity mistake: At the end of the movie, Jack parks the car in front of a palm tree and walks onto the beach. The shot changes while he stands there for a few minutes. As the shot changes back to show him walking off the beach, the car is no longer in front of the tree, nor does he drive by during the credits. I hope he enjoys his walk back to Miami.
Continuity mistake: After the Memphis Belle drops its bombs and scores a direct hit on its target you see the Memphis Belle lift up and turn right with the bomb bay doors closed. The next scene the bombadier says "okay, bomb bay doors, closing" and you see the doors close again.
