Jess' fan fic challenge:

"Set during the episode 1969. Somehow, the team gets separated and
only Jack and Teal'c make it back to the present time. Sam and Daniel
are stuck in 1969 for as long as ... well, as long as you want.
Eventually they do make it back to the present.

Rules: 1. Can be Sam/Daniel friendship, romance, whatever. Cannot be
NC-17.
2. Can be as long as you like.
3. Must include the line "I think we fit in pretty well here."

That's about it. Again, they can be stuck in the past for as long as
you want (even stretching into beyond 1969) but they must make it back
to the present time at some point."

"You! Stop!

The guard, his gun ready, shouted at SG-1 to stop as they stood at the base of the improvised 'ramp', which had originally been the sides of the crate holding the 'gate.

Jack said quietly, "We have got to go," before readying his zat as another guard appeared, readying his own sidearm.

Sam, Daniel and Teal'c dived behind some crates as Jack shot the second guard. The first guard hid behind a Jeep for cover and opened fire on SG-1 after a moment of surprise. Jack zatted the Jeep, and the residual energy charge dazed the guard.

Sam replied, "Sir, the timing has to be exact. Just a few more seconds."

Jack shouted, "It's gonna have to be close enough! Go!"

She replied hastily as she readied her zat, "No, I'll cover you guys!"

He snapped, "Carter!" as Daniel and Teal'c looked on with worried expressions.

"Sir, I'm a faster runner than all of you, so it would make sense for me to be the last one through. With all respect, go!"

The males exchanged a concerned look but realised that time was short, and she continued as the guards began to recover, readying her zat,

"It should be alright now! Move out… Sir!"

Jack remarked, "Who's the Colonel!?"

"Sir, with all respect, you're wasting time!"

Daniel said, "Sam, if you miss this, you won't know when the next solar flare is!"

She replied as she drew the guards' attention, "Hello! Astrophysicist here! Go!"

She became involved in a fire fight with the guards as circumstance forced Jack and Teal'c to reluctantly run through the event horizon, narrowly dodging bullets. Daniel, also reluctant to leave her, was a few seconds behind them, but a stray bullet grazed his calf, taking him by surprise, and he collapsed on the 'ramp'.

Sam managed to zat both guards, before rushing to her friend's aid. She quickly assessed his injuries, her zat aimed at the still unconscious guards. She attempted to help him up but then the event horizon disappeared, the power failing, leaving them both stranded in 1969.
