I thought this was pretty interesting after watching a multi-part series on NASA's space technology in the 1960's. [video]https://www.youtube.com/watch?v=8yPKd7NCdUs[/video] Link.
There are a lot of really smart, innovative people in all aspects of the surfboard construction industry. That was cool, thanks for posting!
I believe its NASA Moon Machines, I think it was on the documentary channel not sure. Its mostly 1960's stuff. I watched it with my dad, he said he helped develop a zero-g oxygen sensor after a fatal fire in one of their tests they had 20% oxygen inside a cabin, and a micro-meteoroid detector too back in that era.
