I do.  Were you there watching on that day?

And I'm sure there was one since.

Yes, I was in that conference room that day.  We were all so proud, so excited because Christa McAuliffe, an american teacher, not an astronaut was going into space on our engines.  We saw it happen, and didn't believe what we saw.  It took a minute or two to sink in, even looking back and forth between the sky and mission control.  So afraid our engines caused the explosion.  Disbelief, horror, shock.  Complete silence, then the crying started.  Men with tears running down their faces, women sobbing quietly.  We were told we could go home if we wanted to, but I believe everyone stayed in that room until quitting time.  It was not a good day.

Yes, Columbia disintegrated during flight in 2003, again killing all onboard, this time caused by a piece of foam debris that broke off a wing's leading edge, striking a plate on the shuttle with enough force to create a large hole, ultimately leading to destabilization and disintegration at re-entry.

We had moved to Nevada by that time, so I was thankfully no longer part of the team, so although very saddened, did not experience the trauma of watching them die first-hand.

Yes, I would still go.  Even at my age I sometimes wonder if my old team ever hires part-time workers.  I do belong to a facebook group for the team that built the SSMEs and get my "fix" that way.  SSME = Space Shuttle Main Engine

US space agency NASA and Elon Musk's SpaceX have picked May 27 for resuming astronaut launches from the United States.

Assumes that all the myriad of sub-suppliers are up and running smoothly by then.

I'll be thinking of and praying for their safety.  Perhaps you could send some thoughts of hope and support their way too, I know you're not much into prayer.  That's not a criticism, BTW, we all have our own way of dealing with things we can't handle or prevent.
