I was a fourth grader. We were going downtown on a field trip that day, and I had just stepped out of the school building to get on the bus when it happened. My school was five miles away from the Murrah Building as the crow flies, and the blast sounded like thunder. I remember several of us looking up, scanning the sky for clouds, and finding none. We sat on the bus in front of the school for a long time, and then the principal got on and said there had been an explosion downtown so the field trip was cancelled. She offered to call anybody's parents who worked downtown to make sure they were okay and told us that we shouldn't tell any of the younger kids at the school about the explosion. We headed back to our classrooms, and without any lesson planned, my teacher brought in a TV. She turned it on and we watched the news for a while, so I actually got to see some of the now-iconic images as they happened. We ended up watching the movie Fern Gully. I was 16 on 9/11 and out of nowhere had the overwhelming urge to watch Fern Gully. A couple of weeks after the bombing my grandmother was in a downtown hospital and had a perfect view of the building from her room. My family went to visit her on a Sunday, so she had Lawrence Welk on. My mind now associates an animated movie and an ancient variety program with acts of terrorism.
My mom was in the last months of residency, and for a couple of weeks after the bombing she worked really late hours. I found out later she was volunteering in the morgue helping to identify bodies. It took me years to be able to visit the memorial, but it's absolutely phenomenal-- the museum especially. I highly recommend it to anyone passing through OKC.
