Stardate 10.3.1988 – Fan conducts unauthorized tour of Star Trek sets.
It was March, 1988, Paramount was in the midst of filming season one of Star Trek : The Next Generation, and two fans unlawfully entered and filmed a set tour. This video has been around for a while, obviously. It has encountered numerous takedown orders, but if the internet is anything, it is persistent. I would recommend enjoying this before it vanishes.
