Other mistake: Beach scene; by the clocks in the control room it's supposed to be just before or at most past midnight (22:52 in Florida, presumably). Explosions nearby, barely past the thick of vegetation, but the team instantly goes to sleep as if they were anyplace safe. To make it more absurd, they awaken in the 'middle of the night' when Polka-Dot Man relieves himself and King Shark tries to eat the rat lady. Cut to the control room, and it's 23:53. It's as if they did not try to move any distance at all. (00:12:35 - 00:29:40)
Other mistake: Bloodsport and the others see the explosions Harley is running from, which are less than a couple miles off. The beach itself should already be lit by the explosions and burning wreckage, which the team couldn't fail noticing as they were approaching. To make the distances more ludicrous, when we see Flag's signal in the control room it's said he's "1 mile north" of them, He's already halfway towards the western isthmus. No reason why it'd take them a whole day to make it to their destination.
