Later analysis revealed the likely cause to be an O ring failure as a sealant due to unusual freezing temperatures before the launch. I’d like to think that the disaster led to new, safer ways to explore space or a determination to solve scientific problems in ways to benefit us all. But thirty years in, I’ve come to realize some of that is probably fantasy, and the reality is a mix of pessimism and pragmatism.

I remember exactly where I was: at the office on Montgomery Street in San Francisco, only six months into a job with a company I would eventually support for decades.

In the middle of an intense debate over something on a spreadsheet, we noticed that everyone was suddenly going into the big conference room with the television, and on the screen was this odd blotch of smoke flowering outward.
