Challenger Anniversary

Today, in 1986, the Challenger space shuttle exploded, with social studies teacher Christa McAuliffe on board. All because of the "o-ring." Do you remember hearing for weeks about an o-ring? I'm still not sure exactly what it is.

Our gym teacher had been a finalist, a fact that she had kept silent until the school assembly later that day. We watched the explosion on TV, although it took a few days to really understand what this all meant. A summary done by one better than I can be found here.
