I work there too, on the second floor. After a rolling shake, the final blast felt like the floor was picked up six inches and dropped!
From my office, we can see down the entire length of the building, and while the windows weren’t broken, there was debris from the ceiling and white smoke. When we evacuated through the fire doors, we could see that the first floor windows had been blown out with glass and debris blasted across the area.
Luckily, those in my office could grab their coats before leaving. I felt sorry for all of the people on the manufacturing floor and the clean room, who may have only had shorts and a T-shirt or the bunny suits. It took a while for some buses to be brought in for shelter.
I’m glad your well fellow freeper.
