|When Mike Weasner shows new hires around the Space Park facility, he always asks if they’re fans of the original Star Trek. If they’re brave enough to admit their fondness for the show, he takes them over to the S cafeteria patio and informs them that they’re now standing on Hallowed Ground. Yes, William Shatner once stood RIGHT HERE!||On February 15, 1967, several scenes from Episode 29, “Operation- Annihilate,” were filmed underneath the walkway. The show aired two months later, on April 13. If you ever catch the reruns on the Sci-Fi network, watch carefully: you can see E2 in the background.||
“Episode 29. Star Date 3287.2. The Enterprise witnesses a smaller ship diving into the sun of Deneva under the control of a pilot who seems to have intentionally killed himself. This confirms Kirk’s worst fears that a seemingly contagious outbreak of insanity on several other worlds has spread to Deneva, where his brother lives. On the surface, many are found to be dead - including Kirk’s brother - and an unknown species of alien parasite is found to be responsible.”
