03/14/69 Season 3, Episode 23 Star Trek "All Our Yesterdays"
So, I was watching old episodes, and for some strange reason, I was drawn to this one. The last 4 minutes of this show.... um, care to guess what happens? And the telling clue, is when Spock says, "Yes it happened, but that was 5,000 years ago, and she's dead and buried long ago." Guess what happens next - a stellar nova that destroys the planet.



1969AD + 2241BC = 4,210 YEARS - close enough for hand grenades or novas it seems. I recorded the last 3:47 of the show on my phone also.
