The Russian space station simulates gravity when it is rotated. The direction that this force applies to people and objects within the station and the two attached shuttles is inconsistent with the geometry of the station. in reality, when the station is spinning in that manner, gravity can be simulated however the two shuttles would experience the gravity a different way, one crew would be able to walk on the floors of the station, where the other shuttle (being on the opposite side) the other folks would end up walking on the celing, appearing upside down to their friends from the first shuttle.
When the asteroid passes the Moon, the scientists discuss the new problem of it rotating in all three axes. The plan was built around the idea of splitting the meteor at 800 feet along a line roughly parallel with the course of the asteroid, so that the two pieces would miss the Earth. The zero barrier was made meaningless because the real possibility existed that the explosion would hurl at least one half of the asteroid directly at the Earth, instead of both pieces away.
During the entire mission, Truman and Grace are at the Johnson Space Center in Houston TX. When the shuttle returns, Sharp says "Kennedy we see you and you never looked so good", meaning the Kennedy Space Center in Florida. When the crew exit the shuttle, Truman and Grace are there to meet them.
Early in the movie, Harry and crew "accidentally" strike oil. Immediately following, when the feds arrive, we see a distinct spot of oil on Harry's nose. In the next few shots it disappears and reappears.
A dog is seen chewing on a miniature Godzilla toy. In the next shot, he is chewing on a much bigger, balloon type Godzilla. But throughout, a guy has been trying to remove the toy from the dog's mouth.
The movie starts on a Friday and they say that the asteroid will hit in 18 days, which would bring us to a Tuesday. The shuttle is launched on a Tuesday evening at 6:30pm. It takes about an hour (67min) to get to MIR, 60 hours to get to the moon, 12 min slingshot, 8 hours on the asteroid and about 4 hours (3:57) to earth after zero barrier. This timeline projects the asteroid hitting earth Friday evening around 8pm. No where near Tuesday evening.
When the space station is on fire, the first shuttle to close up and go (Sharp's, and Harry's) is about to close the door. The fuel hoses are still clearly visible running through the top of the hatch. A second later, the hatch closes and locks - presumably airtight, because it never reopens.
While the NASA team is attempting to override the bomb timer, there is a quick cut to Grace, standing in the observation room looking through the window. We can see the crew down below (through the reflection in the glass). The same exact scene is used after the bomb is detonated. The crew can be seen giving high fives and hugging one another, while they are trying to 'kill the up link'.
In the opening sequence when mission control is talking to the shuttle, the camera swaps between the two whilst Dan Truman talks continuously. On each shot of mission control showing a digital clock in the background, the clock jumps forward 2 seconds the first time and then 6 seconds the second above normal time progression.
During the New York asteroid shower, you see an aerial view of Manhattan with the Chrysler Building. An asteroid shoots from left to right toward the Chrysler Building, but in the shot where the asteroid blasts through the Chrysler Building and the other skyscraper and hits Grand Central Station, the asteroid comes from the right.
It is not Turkish dialect but Azerbaijani Turkish dialect that is heard in all scenes which are from Istanbul, Turkey. Azerbaijani dialect is dominant in Azerbaijan, not Turkey. Azerbaijani dialect is not used in Turkish broadcasts.
The Russian space station is an absurdity in itself: initiating a rotation to accommodate artificial gravity would in reality threaten the structural integrity of such a pronged modular craft, and spinning the station before docking would be unpractical, as it renders a normally tricky docking to be nearly impossible since the docking ports are on the external rotating pods. Furthermore, a rotating station would need its docking area along the axis of rotation, plus the docking vessel would have to match that rotation, and match its center of gravity along the docking point approaching along the station's axis of rotation.
Simulating gravity is possible, but the gravity would be felt only away from the axis of rotation. The way the space station and space shuttles are attached, it would be impossible for gravity to be felt on all normal walking surfaces. And it would not be felt at all at the center. It would be greatest at the walls of the space shuttles farthest from the axis of rotation. NASA has modeled this using 10-30 meter diameter cylinders (like 2001: A Space Odyssey (1968)), and with large systems of a capsule, a 2km tether, and a counter weight. But the smaller the system, the more chances you'd get dizzy if you bent over because the gravity at your feet and head would differ.
Drillers would never use steel cutters on pipe in a hole with known gas pocket/gas residue. Instead, in a situation with known gas pocket/gas residue, brass cutters are used because they don't spark and therefore wouldn't run the risk of igniting the residual gas from gas pocket.
The two shuttles separate their solid rocket boosters and external fuel tanks very close to each other, one just behind and to the side of the other. This would be recklessly dangerous as they could easily impact the other shuttle destroying it.
Cosmonaut Andropov is shown walking normally after exiting the shuttle. In reality he would have great difficulty walking because he had been in a free-fall (weightless) environment for a year aboard Mir.
In reality, it would not be possible to split an asteroid in space with a thermonuclear device, as shown in this film. Most of the physical destructive forces from a hydrogen bomb, is caused by the immense shock wave. Since space is a vacuum, there would be no way for the bomb to create a shock wave powerful enough to split the asteroid in half.
As Eddie Griffin was riding into New York, he passes by a few people who are reading the newspaper that is titled "Shuttle Explodes". Sudden headline news that happened after the latest edition of the newspaper is published would be in the next day's newspaper, not the same day. However the newscaster states that the shuttle exploded at approximately 3:34 a.m. EST; as it is clearly midday there is plenty of time to print a newspaper with the info about the explosion on that same day.
It is presumable that the munitions specialists to supervise the nuclear ordnance would know the full workings of the weapons to include the timers and how to stop the timer through wire cutting. Yet, the Freedom weapons specialist asks Col. Sharp, a pilot, which wire to cut seconds before the timer runs out.
In the psychological examination, Rockhound's solved Rubik's Cube at one point shows a green side adjacent to the blue side. In traditional Rubik's Cubes, the blue and green sides are opposite of each other.
When deactivating the bomb on the asteroid and the timer reaches 30 seconds. The next shot of the timer has been flipped so that it seems read 45 seconds with a reversed 4 (i.e. it actually said 24 seconds).
As the two shuttles are approaching the Russian space station, the pilot of one of the shuttles says he is firing the retro-rockets. This would be done so that the shuttles didn't slam into the station. But as the camera cuts to a view of the shuttles nearing the station, both shuttles are still firing their main rear rockets.
When the shuttles launch and again when the nuclear warhead explodes, the flame of the boosters and the bright flash of the warhead are seen through the front windows on the flight deck, when they would have been behind the shuttle(s).
Killing the uplink to the nuclear weapon would not stop the timer. Once the timer has been started on the nuclear weapon, the timer on it would be independent. It would take an override code via an active uplink, not a killed uplink, to stop it. Thus, Truman's ploy to "buy them maybe two minutes" on the comet would have been useless. What he should have done was use the uplink to stop the timer, not kill the uplink itself.
