When Jillian goes to Washington Square Park by subway, it's clearly night and dark. When she emerges from the subway, it is daylight.
When Spencer and Jillian are at the cocktail reception in New York, Jillian is speaking with the rude woman who criticizes her clothes. As they are walking, they walk past a woman with a large pearl necklace who then kisses the gentleman she is with. Moments later, Jillian walks past the same woman again.
All NASA shuttle astronauts live and work in the vicinity of the Johnson Space Center in Houston, many of them in Clear Lake, a Houston suburb. Yet in the film, Jillian teaches school in Florida, where she and Armacost clearly live. Astronauts only go to Florida for launches.
There is no good reason why all the electricity in the house would short out during the suicide of Natalie Streck as the radio would be on only one of many individual circuits in the house.
When Captain Streck is having his medical episode in the hospital, the medical team is putting an Ambu bag over his nose and mouth while he is thrashing around screaming. A bag valve mask (BVM) like this is a hand-held device commonly used to provide positive pressure ventilation to patients who are not breathing or not breathing adequately. That is certainly not the case here.
When Jill is being examined, she is told she is nine weeks' pregnant. However, the baby shown on the ultrasound scan screen is clearly much more than nine weeks old. Furthermore the movements of the ultrasound probe do not correspond to the movements on the screen. And when the doctor says she will make measurements she never does. Instead she just waits a few seconds before announcing the age of the fetus.
When Captain Streck is having his medical episode in the hospital, the physician is seen sticking a long cardiac needle into Streck's chest to administer epinephrine directly into the heart. This is used during a cardiac arrest to stimulate a cardiac response, but being as Streck is thrashing about and sitting up, that is certainly not happening here at this time.
When examining Reese's things, Jillian comes across a Newsweek magazine with a cover story of the accident in space and a cover picture of a B-58. There is no conceivable explanation nor storyline of why a front line story would use a picture of an aircraft retired practically 30 years before the mission.
Commander Armacost is shown coming out of a coma in his hospital room following his return from space. His wife, Jill, is standing at his bedside. During this time Captain Streck's wife is seen entering the observation room adjacent to her husband's hospital room. Very shortly thereafter Captain Streck has his medical episode while in his hospital bed which lasts a couple of minutes. Astonishingly, Commander Armacost is shown standing in the room with Mrs. Streck standing next to his wife, Jill, to watch this happen. Just moments before, Armacost had been in a coma. Although there is a possible explanation for why this could happen shown later on, no one seems to be bothered by the fact that he is up and walking just minutes after waking up from a coma.
When Spencer checks Jill's pulse at the party, he does it in the wrong place. Pulse is checked below the thumb, while he checks it under Jill's little finger.
