No, cabin pressure was supposed to be at 5 psi in space. From the perspective of the dangers of a fire, it hardly makes a difference if it's 5 psi or 16.7 psi if the environment is PURE OXYGEN. Even 1960's most state-of-the-art fire-proof materials would burn at 5 psi in PURE OXYGEN.

You are partly right. Breathing pure oxygen can cause death (in rats as far as I know). However, test rats only died from breathing pure oxygen after about 30 days. This is from the research done during the time of Apollo. As of current research, I'm not too sure.

I do not intend any disrespect to you or your dad. In fact I admire the work of the Engineers at NASA, it was an incredible feat. The fault was not with the Engineers but the "higher ups" that decided what the engineers should do. For example, there was a report in 1962 that warned about the uncertainty of a pure oxygen environment, and there were countless test- accidents involving pure oxygen environments well before the Apollo fire. In fact, it wasn't until the production of the Apollo 012 craft that the NASA higher ups decided to comission tests of their own with pure oxygen environments, ie they wanted to prove that THEIR decisions right.
The failings were more than obvious even during that time. Oxygen burns well.
HAHAHA I you're right, they are humourless fools. And you call yourselves NERDS?!!! Being a nerd demands flawless use and understanding of sarcasm. *point and laugh*
You are wrong. The mission was ORIGINALLY designated Apollo 204, but then NASA director Webb changed it to Apollo 1 due to a request from Grissom's wife. There's a bit of trivia for you.
I'm going to have to shoot you down on this since I recently did a research project on the Apollo 1 disaster. The craft was supposed to be at 16.7 psi ON EARTH, and at 5 psi IN SPACE. The reason for this was that the engineers at NASA couldn't design an environmental system (either lack of experience or the materials weren't advanced enough, not sure) that could prevent air from outside the craft, while on Earth of course, from seaping INTO the craft.
The danger in this was that the astronauts were already preconditioned to breath 100% oxygen before this. Outside air (of 80% Nitrogen and only 20% oxygen) would have diluted the pure oxygen atmosphere in the craft, and the astronauts would loose consciousness (I think this was what a previous thread talked about that a test with 2 gas system almost killed someone). I'm not sure if 2 psi would be "painful" as someone said. If 5 psi (which was tested on human subjects) were approved for Apollo 1, I think 5 psi wouldn't have been that bad. Keep, in mind that this is PURE oxygen we're talking about. There is a large difference in amount of oxygen in a 2 psi environment than just air in a 2 psi environment.
