I've heard of an incident in the mid 60s: someone was testing a space suit in an vacuum chamber, the suit depressurized and the man fainted after feeling the water in his mouth begin to boil.

It's a good story but I am wondering : does that really happened ?

A quick search in the nasa website didn't gave me anything (maybe i was just using the wrongs key-words)

Does such a story ring a bell to anyone ?

    $\begingroup$ spacesafetymagazine.com/aerospace-engineering/space-suit-design/… , I suppose. (Not sure if credible enough reference for what are you looking for.) $\endgroup$

  • $\begingroup$ Thank you both for your answers ! I did see this but I didn't know if it was to be trusted as it was the only reference I could find... I would have expected someone else to have published something. $\endgroup$ Commented Jan 8, 2023 at 9:36

    $\begingroup$ It's at least referred to in the NASA Engineering and Safety Center presentation here nescacademy.nasa.gov/video/481016c7afb6478c8405a7fdac7f84ce1d See the slide displayed at 22:25 into the video. The website stupidly wants you to log in to download the slides, even though you can see them in the video without logging in. $\endgroup$ Commented Jan 8, 2023 at 17:56
