I heard that a plane crashed into the WTC on my way out of senior english class at my university. I was on my way back to the commuter lot to get home. Then I saw the insane amount of traffic. During the entire drive home (normally 15 minutes) I was listening to the whole thing on the radio. It took me 4 hours to get home because they evacuated downtown and everyone was leaving.
Between that and the Challenger disaster, I'm full of sad memories now.
