Other mistake: McKay and Jackson enters a room and runs into 2 armored figures, Jackson eventually reveals that they are empty suits, however in every shot shot from behind the suits, the suits are constantly moving, as if they are hanging on strings.

1 other mistake in season 5
Starring: Jason Momoa, David Hewlett, Joe Flanigan, Rachel Luttrell
Factual error: Anytime a character fires a missile at an airborne target, it's invariably from an M136 antitank launcher. The M136 is designed to hit relatively slow moving ground vehicles and is useless against fast moving airborne targets. (This is because used M136 tubes can't be reloaded and are very cheap to use as props).
Dr. Rodney McKay: Using power... using power... using power.
Trivia: The show's two hour premier broke the SCI-FI's ratings record by attracting over 4.2 million viewers. It was also the most watched cable program that day.
Question: Why can't they use every last iota of energy they've got and dial earth and ask them to send them any ZPM's that they could find?
Answer: Because even all 4 Naquadah generators (one was destroyed) together is only enough to dial Earth for approximately 1.2 seconds (As seen in the episode "Letter from Pegasus"). Further, if Earth had found a ZPM, they would dial Atlantis and let them know. After all, the SGC has no other use for a ZPM than to dial Atlantis.
