As everyone has heard by now, the space shuttle Columbia exploded upon reentry, killing all 7 astronauts.
I walked into the clinic in a daze and asked my therapist if she'd heard. She hadn't, so I told her and the others there. She switched the radio to a news station and turned it up.
During a break I called home and woke my parents up and told them. My mother was in such shock that she hung up on me.
I remember Challenger. This wasn't supposed to happen once - how could it have happened again?
