This week, TR3 beams down to a “wilderness of arctic characteristics” with our review of the Star Trek: The Original Series episode “All Our Yesterdays.” Kirk, Spock and McCoy time-travel into an alien world’s past in the penultimate episode of TOS, and we time-travel to the original story outline for the show and revisit some scenes that didn’t make the final cut. And of course, there’s a Red Shirt and a Replimat trip. So pay a visit to Mr. Atoz’s library and listen now!
