"Captain’s log, stardate 3289.8. I am faced with one of the most difficult decision of my life, unless we find a way to destroy the creatures without killing their human hosts, my command responsibilities will force me to kill over a million people."
"Operation -- Annihilate!" is this week's new Remastered episode, the one with the flying parasites that take control of the colonists on Deneva. It was the last episode of ST's first season.
It's notable for several reasons, the most obvious of which is the location shooting for the outdoor scenes. This was done at the futuristic-looking campus of the TRW Corporation in Redondo Beach, California, and was one of Trek's most striking "sets".
You can see some Remastered images and read an interview with the producers here, and more Remastered screenshots and FX video at this page. In this version, we finally get to see the ultraviolet light satellites being launched.
