Now I feel really dumb

We all know the space shuttle Columbia broke up during re-entry.

We all know by now all seven on board died.

I was doing a little looking up of the astronauts with some local ties and discovered Dr. Kalpana Chawla worked at the Numerical Aerodynamic Simulation facility at NASA the same time I did. I wrote the User Guide there; she was one of my users.

I don't remember her. She may have been one of the people working in the trailer in the back doing the cool virtual reality stuff, or she may have been working in one of the groups with which I rarely interacted. Nonetheless, I feel stupid, because in theory I worked in the same facility with her and can't remember her to save my life.
