Other mistake: At the start of Rimmer's exam, the invigilator orders the students to "turn over their papers and start". Rimmer reads one side of the paper, then turns it over to read another question. The back of the paper should have been blank as otherwise there would be no point asking the students to keep the papers face down before reading the questions. (00:15:30)

Factual error: While it is true that lithium carbonate can be used to treat depression and other psychiatric disorders, it cannot be administered in gaseous form.

Trivia: "Meltdown" was originally planned to be the first episode of Series IV of Red Dwarf. However, the militaristic tone of this episode - and in particular Dave Lister's strident anti-war speech near The End of the episode - meant it fell foul of the BBC censors. The original planned transmission date (Feb 14 1991) coincided with the outbreak of "Operation Desert Storm" - the Gulf War...and the BBC felt that an "anti-war" episode of Red Dwarf would be inappropriate for a country at war with Iraq.
