Corrected entry: When Jeff Goldblum is demonstrating how he puts the virus into the old alien fighter to lower its shield, he puts a soda can on the ship and asks an officer to shoot it. When he does, the bullet is stopped by the ship's shield. Then after the virus is put into the ship's system, the officer is able to shoot the can off of the ship. But when Goldblum picks the can up, there is no bullet hole in it, only a dent. The military must make their soda cans bulletproof.
Corrected entry: After they had brought the First Lady into Area 51, the doctor said to the President something like:"Your wife has internal bleeding, there is nothing we can do for her, she will die soon." The helicopter crash which caused that trauma was at least 12 hours ago, nobody could survive that time course with severe internal bleeding! Why couldn't those guys at Area 51 operate on her, and how the hell did they even know that she has internal bleeding severe enough to die from? (01:32:00)
Corrected entry: After Randy Quaid flew into the Alien ship and it blew up, what happened to all those Alien Fighters which greatly outnumbered the American jets? There seems to be no further thought of the hundreds / thousands of Alien Fighters in any of the different locations where the Alien Ships are being taken down.
Corrected entry: In the mother ship Will and Jeff light up their two last cigars after transmitting the virus. On the ground contact is lost for "20 mins" - yet when they are picked up on the ground the cigars are still at full length and haven't burnt down a bit.
Corrected entry: The whole premise of the ending was based around giving the mothership a virus to take out the shields. However, given that the "electrics" had only very recently come on in the Area 51 spacecraft, there would have been no time for anybody to have reverse engineered the computer system and alien programming language, let alone for David to come in at the last minute, manage to guess off the top of his head what part of the mothership's system controlled all the shields, find a vulnerability in their code that could be exploited to switch them off, and then create the virus to do so.
Corrected entry: There's no way the people at SETI, NASA, or anyone pointing a telescope at the moon wouldn't have spotted the mother ship long before it reached the moon. If asteroids only a few miles wide can be spotted millions of miles away from the Earth then space ship 1/4 the size of the moon are visible long before July 2.
Corrected entry: The humans are shown attacking the alien destroyers with AMRAAM air-to air missiles, which are shown both times to do virtually no damage to it. AMRAAMs are designed for fast moving air-to air targets, like the alien fighters. Yet, the humans do not see a need to fit their fighters with more powerful weapons, such as bunker busters, cluster bombs, nuclear bunker busters or tactical nukes, that would easily cripple or outright destroy the alien saucer. Instead, they resort to firing countless AMRAAMs at a 15-mile wide destroyer, which amount to pinpricks and cause needless deaths.
Corrected entry: When the president is in the air force bunker inspecting the spaceship, Dr Oken states that the scientists have been repairing it since the late 60's. The president says they've had it for 40 years and know nothing about it. That would mean that the movie would've been set in 2006 and not '96. (01:08:50)
Corrected entry: When Steve crashes his F18 head first into the canyon wall, the nose itself is intact within the fireball into which the alien fighter flies.
Corrected entry: When Will Smith flies the FA18 and is being chased by the alien space craft, just as the FA18 comes into the shot when he flies over the edge of a canyon there is no shadow on the ground, but then suddenly the shadow appears within the same shot - it doesn't gradually appear like the FA18 does.
Corrected entry: When the spaceship is first coming into hover position over D.C., it passes over the Washington Monument. While the shadow hits the ground and monument separately, it incorrectly hits the ground first. Since the light source comes from the left and the spaceship is moving right, it should hit the higher monument first, with the ground shadow trailing. The opposite is true in the movie. (00:22:30)
Corrected entry: When David is calling Connie at the White House, she sweeps the curtain to the right from the outside and she is standing in front of the window. The shot changes angles and the curtain is now being held without Connie standing there. (00:42:10)
Corrected entry: In the scene where Jasmine is running in the tunnel with her child, you can clearly see that the child is a dummy (plastic head). (00:49:20)
Corrected entry: When the White House is obliterated, they made a model of the house to explode. As the beam is on the White House you can already see flames coming out of the left side of the house. They taped it in slow motion, then as the actual plasma/bomb came down through the beam, they sped up the footage. There is no other explanation for this because the "house" is already exploding before it should. (00:47:25)
Corrected entry: I am just curious as to how Jasmine has time to look in the mirror, see the alien plasma wall about 400 yards away, curse, get the slow witted child out, pick up her bag, run to the door, kick the door in and call the dog which gets to them safely. This plasma moves at about 180mph as it was comfortably keeping up with Air Force One when it was taking off. (00:48:35)
