With this being the 50th Anniversary Year of Star Trek, there are a lot of documentaries and we're getting a lot of background of the early years of Trek. However, we're celebrating the actual first premiere of the show on TV (September 8, 1966, as we all know), and before that ever aired, there were two pilots shot, the first being The Cage.
One could make a case that the actual "birth" of Trek would be on the first day of filming, since that would be after all the characters were worked out, the plot was fleshed out, and most of the prep work was completed.
Is there any record of what the first scene ever filmed of Star Trek is and when it was shot? Or perhaps as much as a shooting schedule for that first day of shooting?
