On this day in history.

[Richard Brown]

I was too young to recognize then. But I can imagine from the documentaries I've seen already that this must have been a dramatic and sad day for those people interested in and working on the challenge to go to the moon before the end of the decade. Not to mention the friends and families of the astronauts.

It was a dramatic sad happening. The pure oxygen factor helps keep it on my memory.

Why the pure oxygen factor? Is there a peculiar reason?

It let the spacecraft maintain a lower atmospheric pressure while still providing sufficient oxygen to breathe. A lower atmospheric pressure meant that the weight could be kept down because the lower pressure differential meant that the structure would not have to be as strong to contain the atmosphere inside the spacecraft.

I believe he's thinking of the horrific conflagration inside the space capsule, because of the pure oxygen environment.

Here's NASA's version of events.

I'm familiar with the technical aspects of the Apollo missions. I've read Mike Collins, Gene Cernan, Gene Kranz and Jesco von Puttkamer's books.
What I wanted to know was, why the 100 % oxygen helped him keep in mind.

R.I.P. Challenger crew.

I remember very well. One of the crew members was teacher. She had planned to teach lessons from space.

Her backup on the Challenger mission, Barbara Morgan, eventually went up as a mission specialist on a 2007 launch of the Endeavor.

I detected I didn't read your first post thoroughly. You even mentioned her name! Sorry.

I've seen Barbara Morgan in an interview in "NASA's greatest missions - When we left earth". She and Christa McAuliffe watched Challenger's lift off, the last time before the accident happened.

I edited the post after the fact, her name wasn't there when you made your first response.
