Yet another Mercury program for your Retro Saturday ... This is a 1960 film simply entitled Project Mercury.
The film is mostly about the training the astronauts were doing that year. Although the flights had yet to begin, most of the emphasis is on Atlas orbital flights, not the earlier suborbital flights on Redstone.
At about the ten-minute mark, you'll see a simulation of a capsule sinking due to a missing hatch. One wonders if Gus Grissom recalled this after the Liberty Bell 7 splashdown.
At around the 13-minute mark, you'll see the Mercury Mission Control at Cape Canaveral Air Force Station. Look for a young (compared to Apollo days) flight director Christopher Kraft.
