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.
