My last job was in the section of the Pentagon that got hit. The fluorescent strips along the floor and around the door handles to aid evacuation were a constant reminder. When I’d go outside to check my phone or get fresh air, I’d be right by the memorial, and every couple months I’d visit the memorial chapel down the hall, which has a book honoring the victims. They were everyday GS, contractors, and military, just like me.
I was TDY, but I have many friends who were in the building that day.
