I wanted to leave their time in the past nebulous (at least for this). But if someone else wants to do the historical research and fill it in, please do so. I can see a scene where Clark wants to save MLK and Lois holds him back to preserve history and they are both crying
before the event happens.
I can also see The Tideman Foundation (From The Final Countdown) contacting L&C sometime after 1980.
And if you guys have never seen The Final Countdown - DO IT. It's probably the best thought out time travel story ever done. Seriously. And the sound track isn't bad either. (Enterprise has a theme song and so does Nimitz.
)
