A worthy Endeavour

Godspeed to Barbara Morgan.

Not only was the elementary teacher-turned-astronaut gutsy to blast into space on the Endeavour after being back-up to Christa McAuliffe's ill-fated Challenger flight, but she was doing what all great teachers do -- inspiring kids to go after their dreams.

Morgan rode in the lower center seat that McAuliffe had occupied on Challenger. It took her 21 years to earn that seat, returning to teaching after the Challenger tragedy then becoming a full-time astronaut in 1998. Who says a teaching career doesn't provide for upward mobility?

Safe travel, Barbara -- and thanks to every teacher who lives out his or her dreams in a way that inspires a child.
