Visit https://www.patreon.com/PeriscopeFilm Visit our website www.PeriscopeFilm.com To test designs of new Apollo spacesuits, a large water tank was employed. This film shows a SCUBA diver in the tank, showing how they can easily and quickly move on a metal grid placed in the tank. The grid would then be used in a test with a subject in a spacesuit, negotiating the same grid, for example https://youtu.be/nlAzulVcbFk Interestingly, the Skylab space station's floors, ceilings, and work stations had a somewhat similar metal grid to what is shown here. Shoes with metal cleats were worn by astronauts. The cleats could be inserted into the triangle grid and the heels were rotated to lock the cleats to the grid for stability; rotating in the other direction freed the cleats from the grid. Motion picture films don't last forever; many have already been lost or destroyed. We collect, scan and preserve 35mm, 16mm and 8mm movies -- including home movies, industrial films, and other non-fiction. If you have films you'd like to have scanned or donate to Periscope Film, we'd love to hear from you. Contact us via the link below.
