Oct. 29, 1957 - New, Highly Buoyant and light weight life preserver announced by the US Army: Utilizing the trapped air principle, the US Army's new life preserver weighs less than 3 pounds and does not require oral, mechanical or chemical means of inflation. If the wearer falls into the water, hydrostatic pressure automatically forces trapped air into the upper torso. The body and head are supported even if the wearer loses consciousness. Developed jointly by the US army transportation Corps and Rubber Fabricators, Inc, it will not corrode in salt water and provides full protection to a fully clothed 175 pound man carrying 25 pounds of equipment
