Just for a laugh, I've got an explanation for this 'blooper'.
In 'Terminal', Vila wears a loose Russian-style (side-fastening) tunic over a black shirt. In 'Rescue', he's wearing an earlier season 3 outfit (worn in 'Ultraworld' and 'Moloch'). I've got a theory which is in character.
The enzymes are already eating through the flight deck walls, and Zen has said the Liberator won't survive breaking orbit. Vila knows he will have to abandon ship. He's a very cautious lad and doesn't like the cold, once turning his thermal suit up so high he almost suffered nasty burns. He also remembers his mother's warnings about wearing clean underwear in case of accident or arrest, and having a good stock of it. So he dashes off to his cabin, strips to his underpants, puts several clean pairs on over them, then a spare outfit just in case Terminal is chilly (he chooses one which earlier fitted so nicely under a Fed trooper uniform), then the quite loose outfit he just took off. Of course, before leaving his cabin, he also makes sure he's got his emergency lockpicks, his credit card, and some spare socks.
Once in the Terminal base, of course he overheats and takes off the top outfit, which gets left behind later in the bombed ruins.
Does it fly?
