Corrected entry: Near the beginning the Speaker and his staff refer to the lone agent as Ben instead of Mike. The President's name is Ben. Later on the staff call the lone agent Mike correctly. (00:25:00 - 01:00:00)
Corrected entry: During the air attack on the White House, an anti-aircraft battery pops up from the roof, which then completely ignores the attacking plane, allowing it to fly around machine gunning everyone for a while longer until the fighter shoots it down.
Corrected entry: As the attack begins, a large propeller cargo plane flies towards the White house. Two fighter jets pull up beside the cargo plane before they are blown away with miniguns. The problem is that the fighter jets must travel at two to three times the speed of the cargo plane just to remain stable in flight. There is no way they could fly as slow as the propeller plane.
Corrected entry: How come the president is rushed into the bunker with the whole South Korean committee troop? That couldn't be standard procedure at all. You can trust your own security services, not the ones from any foreign president, no matter how dear and close.
Corrected entry: The president asks his son to choose a tie from a black or brown one. He gives the black one to the kid and keeps the brown one. In the next scene the president has the black tie.
