Apollo’s Worst Day

Interesting recap of the events of January 27, 1967 that resulted in the deaths of Gus Grissom, Ed White and Roger Chaffee.

Fucking gruesome. It's absolutely amazing how even the smartest people in the world can make a mistake like that.

Breathing in pure oxygen feels great right? I've never done it.

Awesome. Especially when you are hung over from drinking with the British troops all night and you have to fix jets bright and early.

It's actually toxic if done too long.

That's wild! I guess humans evolved to breathe air with only 20% oxygen idk. I wanna try some 02 now. All the teenagers are having these 0xygen parties where they dare eachother to breathe pure oxygen for hours on end. Its the latest dangerous trend.

"Prolonged exposure to above-normal oxygen partial pressures, or shorter exposures to very high partial pressures, can cause oxidative damage to cell membranes, collapse of the alveoli in the lungs, retinal detachment, and seizures."

If that is the case, why did NASA decide to use pure oxygen for the astronauts to breathe on the mission? Does it take weeks of breathing pure oxygen for this damage to happen or only a few days?


Do fighter pilots breathe pure oxygen on their flights?

They change the mix for different purposes. Higher oxygen ratio will help you think more clearly and speed up your cognition.
