Apologies - that error is happening again. I went back a couple of times but the same result each time:

Hmm. I haven't been able to reproduce the error on my end. The only thing I can suggest is to try clearing your browsers cache and then re-login to the forum. Maybe there is something cached from the old host, like an old cookie, that is causing the problem.

According to this source, it was pure oxygen, at least in his suit. The capsule was another matter.

From the description it would seem that the capsule had air, changed to oxygen for the EVA.  It didn't mention whether or not the air was brought back into the capsule or not, but as it described the suit was filled with oxygen.

I was under the impression that the Soviets used a nitrogen-oxygen mixture for their cosmonauts after the O2 accident that burned one of their cosmonauts.  But I could be mistaken in that impression.

I believe Leonov did nearly die; after all, he had to depressurise his suit to a dangerous level to get back into the spacecraft.

He reduced the pressure from 40 kPa down to 27 kPa.  This is not a dangerous level, it is more that the Apollo EVA suit (25.5 kPa), and 50% more than the safe minimum for any suit in an emergency (e.g. 18.5 kPa used by by the Shuttle EES).
