January 28, 1986 – one of those days in history. We all remember where we were, what we were doing. Most adults who could, were watching television.

We saw it live: the space shuttle Challenger exploded 73 seconds after liftoff from Cape Canaveral, killing all seven crew members. Flight commander Francis R. “Dick” Scobee; pilot Michael J. Smith; Ronald E. McNair; Ellison S. Onizuka; Judith A. Resnik; Gregory B. Jarvis; and schoolteacher Christa McAuliffe.
