Corrected entry: The only windows in the shuttle are the windshields. How come when the bomb goes off, everyone shields their eyes from the light? I thought they were heading toward Earth, away from the explosion.
Corrected entry: Just after the Independence's Armadillo jumps the "Grand Canyon" on the asteroid, the camera pulls across the Armadillo. Bear is sitting alone in the front seat and we can see him grinning and waving to the camera crewmember. Zoom in and pause to gain full benefit from the "mistake."
Corrected entry: When the two teams visit the space-station, NASA tracks them each through their green "blips" from their locaters. When A.J. and the Russian were locked in the fuel pod, the control team at NASA could see their green "blips" on their screen. The Russian didn't make the trip, why would he have a locater on him?
Corrected entry: As the shuttle comes into land near the end of the movie, everyone got out and went over to their families to hug and kiss them; whilst people in anti-radioactive suits came up to clap them... WHAT.?. Wait firstly, the astronauts have just been on alien grounds. Don't they need to go through some test to make sure they haven't made contact with alien viruses? And secondly, people in these suits don't just come out to clap (although some did go to the shuttle).
Corrected entry: The shuttle makes a far from a smooth landing on the asteroid. It is dinged up quite a bit and even more so while they are there. Columbia burned up because a single piece of ice hit its wing causing the heat shield to malfunction. There is no way this shuttle could have re-entered the earth's atmosphere safely.
Corrected entry: When Harry is taking AJ down the elevator of the shuttle in the end of the movie, neither he nor AJ have their spacesuit helmets on. However, when they reach the ground, they both magically have the helmets on. Where did they come from and how did they get them on so quick?
Corrected entry: In the scene where the window of the shuttle breaks and the air force pilot is sucked out we see him get hit by the other shuttle, fully intact. Realistically the rapid change from pressure to no pressure would cause him to blow up like a balloon and explode.
Corrected entry: En route to the asteroid the shuttles are slingshotted around the moon. Due to the speed and strong curve they're making, the crew is experiencing about 12G. You see the crew screaming like hell and being very awake; in reality, they wouldn't be screaming as the G forces presses the air out of their lungs and it would be very hard to breath. Also, to keep conscious at such high G levels you need to tense all muscles in your lower body to keep more blood in the head, the crew are obviously too busy screaming to think about this. And lastly the crew would probably be unconscious anyway; 12G is a hell of a force and knocks out the most trained fighter pilots around.
Corrected entry: When the rogue asteroid chunk hits Paris and destroys it, they show it later as a huge crater. This impact alone would affect the whole world as we know it. If Mt. St. Helens could spew ash over the states of Washington, Idaho, Oregon and California, then an asteroid the SIZE of Mt. St. Helens slamming into France would surely put the world off-kilter. It's not something that we could go back to the next day and photograph, as was done in the film.
Corrected entry: Even if the asteroid halves fly apart and miss Earth by 400 miles exactly as depicted in the film, it's still going to be a tragedy. The gravitational force created by the asteroid halves as they pass Earth will be about 100 times higher than the gravitational force from the Moon, which causes tidal actions on Earth. Since most of Earth's population lives in coastal areas, most of the world's population will be destroyed in the resulting tidal surge.
Corrected entry: As the 2 shuttles are leaving the atmosphere, the SRB's and ET (solid rocket boosters, external tank) break away at the same time. In reality, the SRB's break away much sooner than the ET, as the SRB's are only used to get the shuttle off the ground.
Corrected entry: At the very end, when the camera pans across the attendees of Grace's wedding, we see the stand-ins and not the real cast. Chick's stand-in doesn't look anything like him and for awhile I thought it was the loanshark, but why would he be sitting in the front row of Grace's wedding? Apparently, those that survived the asteroid couldn't tolerate a Ben Affleck wedding and sent representatives on their behalf.
Corrected entry: To increase the chance of success, there's a backup for everything: we have 2 crews, with 2 shuttles, 2 armadillos etc. However, when we get the crisis where the government wants to blow up the nuke before the hole is finished, there is only one bomb. Isn't there a second nuclear bomb in the shuttle that crashed?
Corrected entry: The asteroid is said to be "as big as Texas." Presumably that means about the diameter of Texas, about 1000 miles. Drilling down 800 feet or meters barely scratches the surface of such a rock, and would merely make a nice crater, not split the rock in two. Drilling 500 *miles* down would have a better chance.
Corrected entry: In the scene when the asteroids hit New York, the dog is hanging in the impact crater by his leash. When they show the overhead shot of the crater you see the body of the Godzilla street vendor halfway laying in the hole. When they show the dog inside the crater the vendor is nowhere to be found.
Corrected entry: Both teams have to drill an 800-foot hole in the asteroid (even though only one team made it to a drilling location). They are doing this in an area that the ground is mostly metal and they are using metal drill bits. The bits the drillers use in the movie are known as "rock bits" and will not cut through metal. There are special bits known as "milling" bits to do that.
