In the film, the astronauts are seen using what appears to be the early concept of the Manned Maneuvering Unit - during the real-life Skylab missions, the Astronaut Maneuvering Unit (the AMU) was tested inside the space station and never tested in the vacuum of space. The first use of the MMU was during STS-41-B (the fourth flight of the Challenger) on February 7, 1984.

There is no musical score for this film. Instead, each spacecraft has its own ambient soundtrack when it is shown in space. The Apollo shots feature a low hum; the XRV, a hollow ringing; the Nimbus Weather Satellite, a rapid series of beeps ascending in pitch; and the Russian Voshkhod, a constant pitch series of beeps. The only exceptions to this is are a very slight, muted bit of music played under the Apollo ambient soundtrack during Pruett's final EVA, and a single tone (with some ambient effects that could be called music) during the opening credits.

At the launch of the rescue craft during a hurricane, the Cape Canaveral press corps is portrayed by the reporters themselves, though they are virtually unrecognizable in rain slickers and other gear. (As related by Sue Butler Hannifin then a space reporter at the Cape.)

The Mediterranean coastline as seen from orbit on several occasions barely resembles the correct geography. Spain is distorted and the Strait of Gibraltar is almost unrecognisable.

The stripe on Dougherty's helmet momentarily disappears while he is flying the XRV-1

The Earth as represented in the on-orbit shots is too small if the spacecraft is supposed to be in Low Earth Orbit (approx 200 miles) as would be expected for an orbital laboratory (and Voskhod) mission. The apparent altitude is more like 1000 miles.

Charles Keith: Look, I've got to get to a telephone!

Charles Keith: Jim... how do you uh... how do you evaluate... the oxygen situation?

Flight Surgeon: [regarding the earliest possible time for rescue] You know of course that by 22:31:06, the crew will be dead. There's not enough oxygen left for three men to live that long.
