Other mistake: During the infiltration in the carrier, Ice Cube steals an M2 Bradley and drives it around damaged for an extended period of time; the flames keep burning with different intensity always at the same spots; one wonders what makes the same point of the armor and the very bottom corner of the back ramp for so long, without spreading at all. (00:56:00)
Other mistake: The establishing shot of the General's house shows still Charlie's car outside in the driveway when Ice Cube gets out of the shower, but for obvious reason it can't still be there - the police convoy is arriving. And of course Ice Cube never hears her drive off or the complex murder setup happening. At the same time, the police IS incredibly quick to arrive. How long did that rugged army man spend in the shower, oblivious to everything? (00:42:45)
Other mistake: Ice Cube just got 'home' after the umpteenth inexplicable escape from the police (he was surrounded by the police with 10 miles radius of roadblocks and they found out about his escape almost instantaneously). The same newscast that reports Pettibone's death reports also that his troops are en route for the funeral. That means that the funeral has been already booked quite literally when his body is still warm. (00:47:50)
Other mistake: Gibbons and Stone have been been together in the same car for over 15 hours at least, from Kansas to Washington DC, and at Lo's they still talk as if they haven't exchanged a single word. (00:19:15)
Other mistake: We know exactly when Darius escaped from prison; 12:06, so, at noon. The moment he gets in the car, he asks to enjoy some carnal pleasures with a burger, and so we see them in the next scene at the burger restaurant...at night. And they haven't talked about anything yet, not even where are they going. So...it's completely unexplainable what they've been doing all afternoon and how could they restrain a hungry Ice Cube all that time. Just a random time skip. (00:13:30 - 00:15:00)
Other mistake: As they drive away from the base stormed by the mysterious invaders, Gibbons mentions that they need to get "off the grid." His watch indicates it's 12:45. The Secretary of Defense informs the President. Who, shocked, reschedules the budget meeting; the clock of the room signals 3:30, but the attack, in Virginia so not in a different timezone, "just" happened. (00:04:30 - 00:07:00)
Other mistake: Gibbons asks for a lockdown, and on screen several doors appear in the map of the facility, in red, but the villains move undisturbed for big corridors past huge metal doors that would have easily slowed their path down if they closed. The movie does nothing to establish if they managed to prevent those doors from locking up, and how - they did not hack the system, they broke in blasting holes from the surface. (00:02:00)
Answer: To break the surface of the water making an easier penetration. Hitting water at high speeds can be like hitting concrete. By stirring up the water it "softens" the impact.
