Corrected entry: In the shot of Fred and Mary Haise at the Apollo 11 lunar landing party Mary is obviously pregnant. Apollo 11 was nine months before Apollo 13 and Mary is supposedly 8 months pregnant at the launch of Apollo 13. She does not have a baby during Apollo 13 and even if she was pregnant during Apollo 11 it would not have showed yet.
Corrected entry: When the astronauts are too shallow for re-entry because they are too light, it is mentioned they should have been carrying 200lbs of moon rock. Yet the lander portion of the lunar module, which is supposed to be left on the moon, is still attached to the ship all the way to jettison before re-entry, weighing far more than 200lb.
Corrected entry: Mission Control in Houston calls up "B.P.C. Clear", meaning that the 'Boost Protective Cover' has been safely jettisoned during ascent. However, the call comes on screen before it is shown being jettisoned.
Corrected entry: Keeping the Earth in the window during the burn for trajectory correction is inaccurate because if the LM were pointing toward the earth, the window would be underneath the craft and the earth wouldn't be visible through the window. The earth is visible to be artistically consistent. This is mentioned by Jim Lovell on DVD Commentary.William Bergquist
Corrected entry: The astronauts are shown taking their suits off before docking, but in real life they were not allowed to do this, in case of sudden cabin depressurization.
Corrected entry: Jim Lovell tells his son that it will take him and his crew 4 days to get to the moon, but when the crew is getting their pictures taken by the media the journalist says Apollo 13 is expected to enter the moon's gravity in April 13, only two days after liftoff on April 11. So where is Lovell getting this 4 days figure from?
Corrected entry: When Lovell is imagining walking on the moon, he looks at the Earth, which is near the horizon. The Earth is far too large (or too close) in the shot, something he would have known as he had seen Earth from the moon on Apollo 8 while they orbited (and took that famous Earthrise photo).
Corrected entry: In the scene just before everyone at the Lovell's residence watches the moon landing on television, Pete Conrad explains how he appreciates everyone coming to his dress rehearsal party for his Apollo 12 landing. In the shot just before he says this you can see Jim Lovell with a cigar in his mouth, but as the shot changes from a wide angle to Pete Conrad speaking you can hear Jim Lovell saying "Oh, sit down Conrad!" How can he be speaking so or at all with a large cigar in his mouth? (00:03:30)
Corrected entry: The film features a portable cassette player. The first commercial portable cassette player (The Sony Walkman TPS-L2) wasn't released until July 1, 1979, 9 years after the Apollo 13 mission. (01:36:20)
Corrected entry: When he finds out he is being bumped to the Apollo 13 crew, Lovell is giving a tour at the vehicle assembly building at the Kennedy Space Center in Florida. In the next scene, he runs into his house, which seems to be in Houston - over 1000 miles away - to announce that he's going to the Moon in April, then races off to get back to training. It seems like an awfully long commute.
Corrected entry: In the scenes where all three astronauts are wearing their space suits, they all have a red collar on the helmet and red markings on suits. The LEM pilot (in this case Fred Haise) would have blue markings and a blue collar so that Houston (and others) could distinguish between the Commander and the LEM pilot when they were on the moon.
Corrected entry: When Deke tells Lovell that Mattingly will have to be removed from the flight, he says that if Lovell is unwilling to go with Swigert, the entire crew will be bumped to a later mission. Even if this really had been Lovell's decision to make (which it almost certainly wasn't in real life), there is no way that all three astronauts could have been bumped to a later mission. Even if the entire backup crew could have been brought up to speed in a week, they could not have flown Apollo 13, given that Charlie Duke (Fred Haise's backup as LEM pilot) had the measles.
Corrected entry: When the astronauts and their families gather around the television to watch the Apollo 11 moon landing, Neil Armstrong is shown on the TV set coming down the ladder normally, top to bottom of the screen. In the actual historical event, the network's TV feed was upside down, with Armstrong appearing to ascend from bottom to top. The surface of the moon appeared at the top of the screen. Moments later, the network corrected the feed.
Corrected entry: In the television interview, when the expert is describing the tolerance requirements for re-entry angle, he asks the reader to imagine that the earth is a basketball and the moon is a softball, and that the two balls are 14 feet apart, which is about 16.8 times the diameter of a basketball. The distance from the earth to the moon is about 30.14 times the diameter of the earth. This means that the 14 feet should really have been about 25 feet. Finally, the expert says that the re-entry angle has to be accurate to within 2.5 degrees, which he says is like aiming for a target the thickness of a sheet of paper. 2.5 degrees at 30 feet is actually about 13.14 inches thick (even at 14 feet, 2.5 degrees is about 7.34 inches).qwer5r
Corrected entry: When Ken Mattingly is watching the launch from a field, he is seen next to a gold and black corvette. The gold and black corvette was a paint scheme chosen for the astrovette which was leased to the Apollo 12 mission crew for a dollar for a year. There were three of these cars, leased to astronauts Pete Conrad, Richard F. Gordon, Jr., and Alan Bean, not Ken Mattingly.
Corrected entry: When Jim comes home to inform his family that he is going to the moon, his teenage daughter comes out of her room to ask is she can wear her particular Halloween costume. Jim eventually says no, and she retreats into her room and the door slams shut. Jim walks to the door and the camera angle changes and you can see that the door is still open.
Corrected entry: Near the end, from one window of the spacecraft you can see a full moon. From the other window, there is a "full Earth." If you're between the moon and the Earth, one or the other would not be full. The sun does not go between the moon and the Earth. (If it did, we would not exist.).
Corrected entry: After Jack Lousma's recommendation to stir the oxygen tanks, Swigert is seen flipping two switches to start the stir that causes the "problem". However, there is a mistake here. Anyone who is familiar with the Command Module Cockpit and Instrument Panel knows that you stir the O2 tanks by flipping the "O2 FANS" to the on position, while Swigert is seen flipping them off. What he has done is disengaged the cryo stir fans, not started them.
Corrected entry: Right before the ship loses radio contact and goes behind the moon, a wide shot shows the ship heading behind the moon. In this shot, the ship casts a shadow into space which can be seen just above the ship. There is nothing nearby onto which a shadow could be cast, any debris from the explosion would be travelling off into space at high velocity in all directions.
