Yep, I was watching it in the physics classroom at lunchtime - on the east coast. There were about 30 students and about as many teachers in there. There weren't many TVs in the school. That was the classroom that had the sample of a shuttle heat tile that NASA sent to schools and my physics teacher set up a little viewing event. My 4th period teacher (right after lunch) was in the room and she said I could stay there and watch.

There were no mobile phones, no social media, no internet. AV had a few TVs on carts (the red asphalt type safety movies were all on VHS by then, though still a lot of film strips/loops still in use). They set up TVs in the auditorium and let students go watch. Hard to get students to focus after that, and the historic nature of the event wasn't lost on anyone.
