Factual error: When the super fortress has a near miss with one of the x-plane pilots the pilot should be in free fall and not appearing to float motionless as the super fortress passes by.
Continuity mistake: 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.
Continuity mistake: 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 mistake: The US flag that was in the back-left corner of Gerson's office (between the map and the window) when Colonel Corvin first visits to offer Team Daedelus' service is gone later on, when General Vostov is in Gerson's office. (00:34:25)
Factual error: After bailing out one of the pilots somehow suspends his free fall and is almost hit by the B29 while motionless in midair.
Visible crew/equipment: When Clint Eastwood first enters IKON to power up the panel, you can see a crew member's hand (with a gold ring) to his right. On his way out you can also see a hand and the top of the head of a crew member in the same location.
Visible crew/equipment: Set lights and camera equipment are reflected in Hawk's sunglasses as he speaks with the kid who wants to go up in his plane.
Continuity mistake: On the reentry James Garner is sitting next to Clint Eastwood - it pans away, then comes back, and no one except Clint Eastwood is in the cockpit. Also one shot shows 4 people in seats during the re-entry.
Factual error: Clint Eastwood and Donald Sutherland go scooting around in open space (admiring a view of Italy on the sunlit side of the Earth) with their gold solar-screen visors retracted wide open. To avoid accidental instant blindness, real astronauts would never open their solar-screen visors during EVA on the sunlit side of the Earth; yet the astronauts in this film do it constantly, with no ill-effects.
Answer: Eastwood would be out on height alone and the rest probably have high blood pressure. https://www.nasa.gov/centers/johnson/pdf/606877main_FS-2011-11-057-JSC-astro_trng.pdf.
