Central time zone morning shows are tape delayed most days, and for the first part of the morning that was the case on 9/11. I was just heading out the door when the Today Show (Katie Couric?) broke in and went live with the video showing fire in the first tower.
Knowing that all air travel was cancelled, it was odd to hear military aircraft on a high frequency tempo leaving/returning to McConnell AFB. And it was super strange to not see any contrails overhead for the next three days.
Lots of aircraft were diverted to our airport, such that IIRC all hotels spaces were taken, and a call went out for volunteers to accept stranded passengers.
My sister and her husband had just spent a work related trip to Italy in early September, where she had met Todd and Lisa Beemer. He is the guy in flight 93 that rallied the passengers to attempt the retaking if the plane, which resulted in the Shanksburg crash. That really tore them up.
