Corrected entry: When the space shuttle is in outer space several explosions and scrapings occur. The audience hears each of these. These sounds would never be created in the first place because space is a soundless vaccum.
Corrected entry: 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.
Corrected entry: Just curious - we first meet the characters in the year 1958 when they were test pilots. In real life Tommy Lee Jones was about 12 years old in 1958. The Eastwood, Garner and Sutherland characters' ages made more sense. They would have been in their mid to late 20s in 1958. Oh well, it's still fun watching these four stars together.
Corrected entry: Clint Eastwood orders everyone to bail out, since his landing is likely to be a spectacular crash. Donald Sutherland blows the hatch and obligingly throws out the two disabled astronauts, though he and Garner stick with Clint through the hairy landing. In all the excitement, Clint forgets to tell NASA that two unconscious guys are now descending into the ocean by parachute, and must be rescued before they drown.
Corrected entry: As the shuttle approches Ikon, their rader activates the on-board systems. But they are in space. Radar is a sound based system and sound doesn't travel in space.
Corrected entry: In the scene where Frank confronts Gerson in his office about not sending them into space, you can clearly see that the second hand on the clock in the background is not moving.
Corrected entry: When the astronauts finally get to IKON, everyone is amazed at how big it is. Now come on! Russia begs the U.S. to fix their satellite, NASA spends about a billion dollars getting a mission up there, man-years are spent training astronauts, and they don't even know what the satellite looks like?
Corrected entry: 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.
Corrected entry: During the countdown to liftoff, the main engines are fired at T minus seven seconds. In reality, they are fired at T minus three seconds.
Corrected entry: When Clint is out of the shuttle, you can see a reflection of the Earth in the visor. On the outer shots you can tell he's at a fairly low altitude in comparision to the distances reached be Apollo. Yet, you can see the whole Earth in the visor - he is far too close to be having reflections of the complete Earth.
Corrected entry: The Russian satellite was said to be 1,000 miles up. They should have known it wasn't a communications satellite because they are 23,500 miles up in geosynchronous orbit.
Corrected entry: When Eastwood leaves the cabin in his space suit, he fails to close the airlock hatch door and proceeds to the MMU station, yet when Sutherland comes out the door it has been closed. Eastwood is the only one who could close the door as the others would have no way of accessing the hatch into the shuttle bay.
Corrected entry: When the team is preparing for Blast off they all pull down their visors prior to launch. Before the visor is pulled down Jerry doesn't have his sunglasses on, yet immediately after he pulls his visor down they're on his face.
Corrected entry: In the first mess hall scene, Eastwood has his ID card but after the young astronaut team sends them drinks the ID card is gone but is seen again in the next shot.
Corrected entry: The Junior Astronaut pulls a plug on the dodgy Russian satellite and explosion follows following which the shuttle is hit by debris. There is a small fire in the shuttle. The smoke goes up. As the shuttle is supposed to be in weightlessness this means smoke will hover around the fire rather than go up (the fire could in theory extinguish itself due to carbon dioxide building up near it as well (which would normally go down to the floor as it is heavier than air) (for the physicists amongst us: that's why a candle can't burn in weightlessness).
Corrected entry: Have you ever heard of them re-naming a shuttle based on the first team that flies it?
