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.
Chosen answer: Report 30185 is a joke report referring to the time when SG-1 go back in time to 1969 in the episode '1969'. The joke is that Colonel O'Neil knocked up a hippie and made sure Mitchel was taken care of throughout his life, like how he got into the 302 program while his buddy, a better pilot, did not.
