| Feb 15, 2020 at 23:36 | comment | added | John K | @Jpe61 yes thanks for the correction. It might be better to say you'd get the bends right away. The bends could be a problem for some unpressurized aircrew in WW2 at 25000ft. | |
| Feb 15, 2020 at 22:57 | comment | added | Jpe61 | @JohnK if you are referring to the Armstrong limit, no, blood would not boil because of blood pressure, not even close. Saliva, sweat and moisture in the lungs would. Fun fact: If you were flying at or above the Armstrong limit without pressurisation, and (as your last deed) decided to take a leak, you would piss steam. | |
| Feb 15, 2020 at 22:47 | comment | added | Jpe61 | @TomMcW yes, sort of. For example one of the reasons concorde had such small windows was that if one of them broke, the pressure loss would be slower. | |

spelling: decent -> descent

| Feb 15, 2020 at 15:40 | comment | added | TomMcW | @John K So Concorde was really pushing it at FL600? | |
| Feb 15, 2020 at 15:38 | comment | added | TomMcW | So Concorde could do it because it could descend at high speed. Makes sense. I wonder if Concorde ever had such an event. | |
| Feb 15, 2020 at 15:13 | comment | added | John K | You could also point out that at 63000 feet blood boils at normal body temperature, which means if you go above the low 50s without a pressure suit you are getting dangerously close to instant death if you get a decompression. | |
