Ep 21. 1969

Stargate SG1 season 2 episode 21, titled "1969," follows the SG1 team as they accidentally travel back in time to 1969 after passing through the Stargate. They find themselves in a different world with different technology and a completely different culture. The team must work together to find a way back home, but before they can do that, they must first adjust to the times and figure out how to blend in.

Captain Samantha Carter, Colonel O'Neill, and Dr. Jackson quickly realize that they are in the midst of a pivotal moment in American history - the height of the Cold War and the Vietnam War. They also quickly realize that their presence could potentially change the course of history if they are not careful. Meanwhile, Teal'c, being an alien, is not able to blend in with the humans in the same way as the others, so he stays behind to guard the Stargate.

Desperate to find a way back home, the SG1 team ends up at a local bar and meets a group of hippies who are sympathetic to their situation. The hippies offer to help the team blend in and lend them clothes, shelter, and advice. They even help them obtain fake IDs to avoid any trouble with the authorities.

While the team is trying to blend in, they also attempt to find any technology that could potentially help them return to their present time. They stumble upon a NASA facility and manage to sneak in. They meet the head of the facility, who is skeptical of their claims but eventually agrees to help them. The team later finds out that the Soviet Union has launched a missile towards the United States, and they must find a way to stop it before it causes a catastrophic event.

As the team races against time and the changing course of history, they must also deal with the inevitable culture shock that comes with time travel. They witness firsthand the harsh realities of the war and the struggles of the people during that time. The SG1 team also find themselves forming emotional bonds with the people that they meet in 1969, making it even harder for them to leave.

Overall, "1969" is a captivating episode that combines science fiction, drama, and historical fiction. The team's adventure through time paints a vivid and accurate portrayal of the era and the tensions that defined it. It also raises thought-provoking questions about the potential consequences of time travel and the importance of understanding history.
