Visible crew/equipment: When O'Neill, Carter and Quinn meet Teal'c at the ship wreckage, the camera moves to focus on O'Neill. The shadow of a boom mic on the ground follows his path. (00:02:05)
Disclosure - S6-E17
Plot hole: Senator Kinsey references the Foothold incident from season 3, yet only a few episodes before it was revealed that Kinsey could never have known about it because it was covered up under presidential orders and he especially was not in on it.
Unnatural Selection (2) - S6-E12
Other mistake: When Thor reveals to SG-1 that the Replicators have reversed the time dilation device, he says time is moving at a factor of "10 squared" (100 times faster than real time). Carter says that in the hour that passed, 4 days have passed for the Replicators (which is correct), but then says depending on when they did it, hundreds of years could have passed. But that's not possible since that means years in real time would have passed. But the Asgard didn't set this trap years ago, just recently.
Continuity mistake: When Samantha Carter is locked in the storage room on deck 7 and she uses the plasma cutter to make a hole in the door, there is a fingerprint on her visor which appears/disappears between shots. (00:25:30)
Continuity mistake: When Jack is revived in the sarcophagus after being caught, the first shot of this his shirt is in perfect condition, but in the next shot of it, there is a knife hole in the shirt which disappears when he is being taken to the "anti-grav torture wall"
Deliberate mistake: In the scene when the timer exceeds 38 minutes, said timer is displayed in big digits on a computer screen. There is a shot of General Hammond with the Stargate in the background. There is a pane of glass between the General and the Stargate. In the shot, General Hammond turns and looks at the gate, and then the camera's focus changes from the General to the Stargate itself. In doing so, a reflection of the timer in the pane of glass is also brought into focus. However the timer is displayed correctly when it should be flipped left to right as all text is when it is reflected in either a pane of glass or a mirror. On the DVD, the writers revealed that this was done on purpose so that the viewer would have a concept of the time running out even when the timer wasn't in shot. (00:17:30)
Continuity mistake: In a scene where Sergeant Walter Harriman tells General Hammond that SG-1 is ok, but Dr. Friesen is dead, Sergeant Walter Harriman is wearing the uniform of Major Davis (you can see "Norman Davis" written on left side of his chest). [His name was originally Norman Davis. At one point, Hammond refers to him as "Airman". This was misinterpreted as him being called "Harriman." Then, in the episode 2010, O'Neill calls him Walter. Thus, his name changed from Norman Davis to Walter Harriman. Still a mistake, but that's why.] (00:30:15)
Other mistake: When Jonas says he has flashes of what's going to happen (and no-one believes him), Teal'c says they have encountered many strange phenomena but no-one who could see the future. Except Jack and Teal'c had a whole "Groundhog Day" episode where, because they were stuck in a loop, they could see the future. Carter then says it goes against all the laws of physics as we know them, despite knowing time travel and other things that break the laws of known physics exists.
Chosen answer: It's never actually mentioned on the show, though in the 'Continuum' universe, she says she's been with Ba'al for 50 years.
