I was on my second day of a week-long break from work, so I was enjoying being able to sleep in a little bit. My phone started ringing around 8:20AM, but I let the answering machine (wow...we actually had answering machines back then) get it. When it started recording, I heard my mom's voice saying "Hope you're having a good vacation. If you're home, turn on the news...something terrible is happening." I got up and turned on the TV, and watched in disbelief as I saw the smoke billowing from the two towers. As I was watching, WTC 1 came down.
My mom's building on the old Lowry AFB was evacuated shortly thereafter and she came to my apartment so we could be together and watch the news to try to figure out what was going on. When the Pentagon got hit, that really horrified both of us...we had 5 friends who were co-workers of her's who had left the previous evening on a TDY assignment to the Pentagon. Luckily, since their flight got into DC so late on Monday night, they were all allowed to report late. They were walking toward the building when the plane hit it, so none of them were hurt.
10 years later, my mom retired as the only civilian to have ever served in the position she held with the Air Force, after almost 38 years of service. Just a couple of days before her retirement ceremony, Osama Bin Laden was found and killed. During the ceremony, we all sort of joked about how that was her retirement present from the SeAL team. She had spent that 10 years mobilizing Air Force Reserve personnel as part of the GWOT, so it was the icing on the cake. My brother, who was a Staff Sergeant in the Air Force Reserve that day, was one of two Airmen who conducted the flag ceremony. Before moving into the Air Force Reserve, he had been a Staff Sergeant in the Marine Corps, and had served in both Iraq and Afghanistan. Everybody in the family was together, at home, and safe.
