Continuity: The character Jerry, played by Donald Sutherland, snaps off one arm of his sunglasses that the doctor gave him. He uses it to assist him in fixing the door that was jammed shut. When they are suited up and coming back to Earth it shows him with the sunglasses back on from both sides of his head and the arm is on the glasses, not broken off anymore.

Continuity: In the opening shot of the NASA people, they are wearing I.D. tags that have the date of 11-99.  But just days later Clint Eastwood's tag is a year higher, showing 11-00.

Continuity: When Donald Sutherland is getting off the roller coaster to talk to Clint Eastwood. He kisses the woman and then removes his glasses. You then see a shot of the back of his head and his glasses are still on. They then show a shot of his face and they're off.

Other: Each STS, or Shuttle Transport System, mission is given a sequential number. STS-1, STS-2, and so on. As of November 2001, NASA was only on its 108th STS mission, yet this movie, which takes place in 2000, refers to a mission as STS-200.

Factual error: They only have a month to train. In that time they would train for the mission and just let a trained pilot/commander fly. Also, they wouldn't take time out from training to go to CA to be on Leno.

Continuity: When the Shuttle is landing at the end of the movie, the wing says Discovery. Earlier they specified that the shuttle they took up was a new shuttle and that it was named Deadalus.

Factual error: Several times in the film you see astronauts "suit-up" and head straight out the airlock into space. In reality they would have to pre-breathe pure oxygen for forty minutes to purge the nitrogen from their bloodstreams. If they just went straight out they would suffer from "the bends", as divers do.

Factual error: The Russian says that the missiles in IKON are locked onto American cities. The implication is that those cities will be destroyed if Eastwood screws up. Actually, since the orbit has decayed from geosynchronous (an altitude of roughly 22,000 miles) to low Earth orbit at 1000 miles, I don't think the missile guidance systems would get a chance to work. If the missiles were launched, they would simply shoot down toward the Earth and blow up wherever they happened to be. So, prayers to anyone unlucky enough to be directly below those missles.
