Very cool ! I used to love those stores. I bought a lot of neat things in the surplus stores. In the 60s we bought WWII military clothing, life vests, sleeping bags camping equipment etc. I don't know if any were surplussed but the U.S. Gov't and Goodyear Rubber made 12 inflatable airplanes for rescue /emergency purposes back in the 50s. Popular Mechanics had a great article on this inflatable airplane. It inflated just like a rubber boat and had small gas engine. When you are a kid you can really dream up some great James Bond adventures with a rubber airplane!
