Pressure

From what I have read elsewhere, the internal oxygen pressure was 5 PSI, which was much lower than the 14.7 PSI outside. So why does this article describe it as high pressure? Also the plug door would be easier, not harder, to open outward, but rather was hard to open because of the closure method (fasteners and the like).

As an aside, all three lives could have been saved if they had equipped the launch tower with a flushing hose having an explosive head to penetrate the skin wherever it was placed in order to blow in cooling and smothering N2 and suck out the O2 along with any combustion products in a matter of seconds. But then they thought “what could possibly go wrong?” — Preceding unsigned comment added by 98.41.92.239 (talk) 06:50, 27 November 2022 (UTC)

Hope you don't mind, I pasted your comment here at the bottom of the page to keep things in order. Sourced info in the article states that "After the hatches were sealed, the air in the cabin was replaced with pure oxygen at 16.7 psi (115 kPa), 2 psi (14 kPa) higher than atmospheric pressure", and that "The heat of the fire fed by pure oxygen caused the pressure to rise to 29 psi (200 kPa)". The plug door was sealed by high pressure, so extreme high pressure (as present in the fire) would render it utterly incapable of opening. Also having a hose attached would have been impossible, since the idea was - you know - going to space, where there aren't any hoses. I'd suggest giving the article and its sources a thorough read-though, I believe it would answer a lot of questions you might have. NekoKatsun (nyaa) 19:59, 28 November 2022 (UTC)

Vandalism in audio recording captions

Someone made a change to the captions in the audio recording in the "The Fire" section so they are obviously inaccurate and include references to memes. 8.52.175.76 (talk) 20:27, 21 May 2025 (UTC)

Good catch, thank you! I've reverted the vandalism on the Commons file captions. NekoKatsun (nyaa) 20:41, 21 May 2025 (UTC)

Bio of Gus Grissom

I have added a "webarchive" link to the link to the biography of Gus Grissom at https://history.nasa.gov/Apollo204/zorn/grissom.htm , as "history.nasa.gov" does no longer exist and this page has not been moved to "www.nasa.gov/history/" like some other pages.

However after searching I found the contents of the page are also published at https://www.nasa.gov/missions/apollo/apollo-1/detailed-biographies-of-the-apollo-1-crew/#hds-sidebar-nav-3 - albeit not on a page by itself, but together with the other astronauts that died with Apollo 1.

What is the better choice? WebArchive, or the link to the composite page (with the seemingly generated anchor which might easily change)?

Citation 48 is now a dead link

Citation 48:

1. "Apollo ECS Fire at Airsearch Torrance Facility, April 28, 1966" (PDF). Apollo 204 Review Board Final Report. NASA. pp. D-2-25–D-2-26.

leads to a dns error and needs replacing.

Thank you to whichever brave knight takes up this cause. ~2026-57262-4 (talk) 01:34, 27 January 2026 (UTC)

Fixed it; good catch! Also I like being called a brave knight, thanks for that ^^ NekoKatsun (nyaa) 16:31, 27 January 2026 (UTC)
