That was 7th grade for me, a teacher came to the door of my history class and whispered to our teacher who sat back down and broke the news to the class. We had a discussion about what we thought might have been the cause. Being the young conspiracy theorist I was, I riffed off the fact that the Soviets were jealous of our proficiency in space and had used Star Wars type laser weapons to burn a hole in the ET and blew it up from afar.I was in 4th grade when the Challenger blew up I think.
Was sitting on my girlfriends patio who lived across the street from Navy Avionics.... Tripped us out seeing all the activity after the news aired it.....
