Continuity mistake: When they are drawing straws to see who stays on the asteroid, they show AJ pulling his straw. It's the same length as the other straws shown, but when it cuts back to AJ he all of a sudden has the short straw.
Continuity mistake: The front of the space shuttle explodes twice. After we see it explode the first time after it first gets bombarded with projectiles, in the very next shot, we see the front half of the plane with two crew members floating around inside at which point we hear: "Houston!". Then the front part of the shuttle blows up again.
Continuity mistake: When the drillers are getting checked out at NASA to see of they are o.k. to go into space, the fat white guy is wearing a robe that is covered with blue dots. The next time we see him, he is in a plain white robe.
Factual error: In the Paris meteor scene, the POV is from the walkway of Notre Dame cathedral, with a very famous gargoyle in the RH side of the frame. From that POV, the Eiffel tower is visible, but the L'Hôtel national des Invalides (Napoleon's Tomb, the gold-domed building in the foreground) is in the wrong location. To show both of those structures in those positions, Notre Dame would have be located about a mile southwest of its actual location.
Visible crew/equipment: During the scene when the crew is trying to disable the bomb, the camera pans in from a wider shot to a close up twice, once at the start of the scene and once towards the end. During the second pan, on the left side of the screen, the matte box or some other part of the camera can be seen.
Revealing mistake: When Ben Affleck riddles the shuttle's fuselage with the bullets from armadillo's gatling and then rams it to get outside, it can be seen that the side wall of the ship is paper thin. Now, I know titanium is a sturdy stuff but don't believe such a flimsy construction would be enough to stand the ordeal of a space flight with gravity loads during the start, escaping/entering the atmosphere and pressure difference in the vacuum of space.
Continuity mistake: When Harry goes into A.J.'s room, he gets mad and sticks the end of a putter golf club at A.J.'s throat. The next scene the club changes and is not a putter anymore.
Deliberate mistake: When the bomb is going to be remote detonated, on the inside lid of the briefcase, the remote destruct warning says that upon activation, the warhead will detonate in T minus 10 minutes. When the countdown begins on the bomb however, it is only for 6 minutes.
Continuity mistake: When they are boarding the shuttles, Harry and AJ have a brief chat and they get onto to bridge last. But somehow Harry manages to get in front of Rockhound and Max, and AJ manages to get in front of Oscar and Bear.
Audio problem: When Freedom shuttle is being destroyed by the asteroid field, you can hear Harry say, "Sharp, what the hell is that? Is that the Independence?" but you can tell by Bruce Willis' mouth that he isn't saying any of those words.
Continuity mistake: When the team meets the flight crews for the shuttles, there are two munitions specialists - Gruber and another astronaut. We see this other astronaut board the shuttle, then he's never seen again, not even his body.
Continuity mistake: The first shuttle takes off some time before the second. Nevertheless we see a picture of both shuttles in the air shortly after they clear the towers.
Factual error: During the opening shot of the shuttle Atlantis in the satellite repair scenes, its cargo bay doors are closed. Standard procedure for orbiting shuttles was to keep its cargo doors open, for a variety of reasons, not the least of which is that the airlock is located within the cargo bay. The astronaut isn't tethered but using an MMU, but still would have to enter and exit through the cargo bay airlock, meaning if the doors where closed, if there were an emergency he'd have to wait for someone to open them before he could get back in.
Other mistake: When the first shuttle has crashed, you can see that one of the characters (I think it was Liv Tyler's fiancé) has torn gloves. That would decompress his spacesuit and he'd suffocate.
Audio problem: During the sling shot around the moon we hear a sound in more or less every shot of jet engines being revved up. They couldn't rev the engines up several times - it's not like such engines have gears.
Audio problem: When the Russian space station is on fire, and the crews are running out, you can hear Harry say, "Where's the rest of the team?" but his lips don't move.
Continuity mistake: As Harry's crew is about to start drilling, Rockhound analyzes the surface. The drilling head is already bellow the asteroids surface. When the camera pans back to Rockhound the drill head can still be seen slowly turning on the upper right corner.
Factual error: The military sends a signal to the drilling team's nuke, arming it and triggering a countdown. A sudden rush to disarm the warhead ensues, with the NASA team on Earth temporarily breaking the uplink and stopping the detonation countdown. However, modern nuclear weapons do not require a "constant uplink" to detonate. Once the signal is sent and the nuke is armed, the signal can be cut or interrupted and the nuke will continue counting down.
Revealing mistake: When AJ drives through the wall in the spaceship wreckage, the material flaps about in a very un-metallic way.
Factual error: When landing back on Earth, the Colonel says "100% flaps." Flap positions are graduated in°, with the extreme position being full flaps (40 to 50°).
Chosen answer: Because there was no real need for him to talk.
