Visible crew/equipment: After taking the enzyme, Mckay is talking to himself as he dials the gate. When he goes to push the centre button, an arm moves on the opposite side of the DHD. (00:09:35)

Stargate: Atlantis (2004)
1 visible crew/equipment mistake in season 2 - chronological order
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: If he's so worried about global warming, why did he fly us here on a private jet that spews out more CO2 than Sweden?
Trivia: In the final episode, 'Enemy at the gates' Sam Carter says that the new ship is to be named the General George Hammond in memory of the character Hammond who had died of a heart attack. This is a tribute to Don S. Davies, who played Hammond, who sadly died of a heart attack in June 2008, shortly after filming Stargate Continium.
Question: It was said earlier in the show that the Atlantis crew did not have enough power to dial Earth. Earth Control had no idea of the fate of the Atlantis crew until they sent the video package telling them what was going on, then Earth Control sent reinforcements to help out. My question is; if Earth Control was able to send reinforcements to Atlantis to help out, why could they not send a crew to check on the status of Atlantis? They knew the Atlantis crew made it in the 1st episode.





Chosen answer: Because the ZPM allowing them to dial Atlantis was being used at the Antarctic defense outpost. They couldn't risk making Earth vulnerable to attack from Anubis by depleting it with repeated dialing to the Pegasus galaxy. Once they knew Atlantis was in serious danger, they had no choice.

ZPM from Antarctic was depleted in first dial, dial in Siege was done via ZPM from Egypt (SG-1: Moebius Part-1/2).
