When Columbia meets Starflight One the first time, it rotates such that the two craft are nose-to-nose, but then Columbia is immediately seen from Starflight One's passenger windows, without sufficient time to move.

In many scenes, including the escape through the tunnel, there is visible evidence of gravity being present, while the spacecraft is in a zero gravity environment.

A second space shuttle appears near the end. It is identified as Columbia and then a number. This implies there are two shuttles with the name Columbia, which is unlikely, even in science fiction.

The footage of a rocket referred to as "Delta" is clearly that of the Saturn V moon rocket.

The Space Shuttle Columbia launches multiple times in one day, once with a two hour turnaround time. The absolute minimum turnaround time planned for the Space Shuttle orbiters was two weeks. However, the fastest actual turnaround during shuttle program history was 54 days, performed by the orbiter Atlantis on mission STS-61-B.

Refueling of Starflight One from Columbia takes an implausibly short period of time.

As Josh Gilliam is being transported in space in a sealed coffin, a small leak happens. It is Minus-260 degrees in space, he would die (get frozen) instantly.

Rockets need an oxidizer in addition to fuel. The dialog says that Columbia will refuel them with liquid hydrogen. They would also need liquid oxygen, just as Columbia needed liquid oxygen.

The casket Josh is using is described as being hermetically sealed, yet while he is getting situated, the casket is plainly a non-sealing gasket, which is evidenced by the lack of a gasket between the body and the lid. In addition, when he is shining his flashlight around the interior, he is not shining his light at the space between the lid and the body, yet Cody reports there are no light leaks.

The outside footage of Columbia preparing for its second launch is not of Columbia, but rather of the test orbiter Enterprise mounted in launch configuration during fit-check procedures in 1979. Columbia's distinctive black wing chines and other markings on the forward fuselage and vertical stabilizer are missing. The footage after launch is again Columbia, as Enterprise was never actually launched into space.

The handset on the passenger telephone has a port for a cord at the bottom, yet there is no cord between it and the cradle.

In several scenes, objects are shown floating while others around are not.

Small light wires can be noticed levitating objects (esp. the gold bars).

The closing credits (in Roman numerals) show 1982, not 1983.

The passenger tube explodes killing the five passengers who were moving through it at the time. No mention is made of the Columbia astronaut who was leading the group who should have been killed as well. In addition, the hatches on both the Columbia and Starflight would have then been open to the vacuum of space after it exploded and broke away causing additional casualties aboard the shuttle.

The Starflight craft is seen going upside down in space a lot of the time. Yet, there are no shots shown of the crew or passengers upside down.

About 30 seconds after Starflight One takes off, the copilot reports "positive rate of climb". This call is normally made almost immediately after leaving the ground, not 30 seconds later.

A character refers to koalas as "koala bears". Koalas are marsupials, not bears.
