Visit https://www.patreon.com/PeriscopeFilm Visit our website www.PeriscopeFilm.com To test designs of new Apollo spacesuits, and to understand the types of tasks that astronauts could perform in low or zero gravity, a large neutral buoyancy tank was employed. This film shows SCUBA divers and a test subject in a spacesuit in the tank, negotiating using handholds on a grid which is made up of hexagons. (Note: the grid is a bit hard to see in the film). Similar grid-like structures were used aboard the Skylab space station. 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. This film is part of the Periscope Film LLC archive, one of the largest historic military, transportation, and aviation stock footage collections in the USA. Entirely film backed, this material is available for licensing in 24p HD, 2k and 4k.
