The CIA claims to have made this video in 1960 for the families of those working on the U-2 project. Running about 20 minutes, the video goes into detail about how the U-2 came to be, what it was meant to handle, and some of the pitfalls that came with the project (i.e. 18 worker deaths). Most of this video is filled with matter-of-fact information you've already read or heard about a thousand times regarding the U-2 planes. However, one detail the mini documentary mentions toward the end may surprise you.
You already know that people working at Area 51 weren't allowed to mingle or talk shop with workers in other sectors, but did you know that the workers weren't even allowed to leave the base except to go home? Las Vegas, which according to the video is just "72 air miles away," was totally off limits to Area 51 laborers, as was virtually any town outside the base for recreation. The workers would have some games to play, like volleyball, pool, and the occasional movie, but other than that, not much else. The environment sounds more like a prison than a workspace. Apparently, there's a big price to pay when you're genius enough to be recruited to the most secretive base in the world.
