Yes, this. I remember Challenger and Columbia very distinctly. I watched both live.
As a fan of NASA since childhood, both of them hit me really hard. I had to watch today's coverage until the astronauts walked off the helicopters and into the navy ship.
During the communications blackout on re-entry and I was shaking - right up until they got the response from them.
I've had an extremely bipolar day but this was a relief. Challenger, Columbia, and yes, Apollo 13 were all on my mind.
