Revealing: Another fly-by-wire act by Joseph Bottoms is in the scene when the Cygnus is first sighted and he vaults himself over the Palomino controls (in low gravity) to reach his seat. As he settles down, the wire used for the vault is briefly visible on his belt.

Factual error: In the PALOMINO scenes, Anthony Perkins wears a long lab coat. In most of the scenes, it hangs straight down; but in the low gravity aboard the ship it should be flattering about (that's why such loose garments are not worn by real-life cosmonauts; they would be a hindrance).
