jfk - got home from school and dad was watching the news on tv.

1st shuttle explosion - my youngest son was a baby I was feeding him and it came on tv , the rest of the day I just held him and cried a lot

9/11 - at work many of us had radios, friend said "a plane crashed into some buildings in NY" I was thinking a small plane , not a airliner LOL.
then everyone turned up their radios to the same channel and everywhere we went we could hear it all unfolding.
not too much work got done that day.. management set up some TVs in the cafeteria too.
