For me, the Challenger tragedy sticks out because it happened during my senior semester in college while I was student teaching. Right after taking attendance, my third grade class, along with nearly every other class in the school crammed into our school's library to watch. Given this mission was all about the teacher , Christa McAuliffe, teaching students from space, this was likely happening all over the country. It was shocking for all of us and hard to know what to say to the kids when it happened.
