I was scheduled to go out on Nuclear Alert that day to man a Peacekeeper ICBM Launch Control Capsule with my crew partner. I turned on the news before I left the house and was watching footage of the first tower smoking, and then saw the second plane hit. I couldn't watch too much more of the footage as I had to leave for our Pre-Departure briefing, which as you can imagine was very stressful and full of uncertainty. Ultimately, it was decided that the breadth of the threat was unknown and they wanted to reduce our footprint, so it was decided that we would not be traveling to our alert facilities that day. Instead the crews who were already out there pulling alert, and had almost completed their scheduled 24hr alert, would remain and pull alert for another day..... They got extended again, and ultimately pulled a 72hr alert. The sucky part for them, is that we were not yet in the "Mandatory Cold Weather Gear" time of year yet, which starts in October. During that time, you always plan on unexpected weather rolling in which may prevent crews from coming out to relieve you, and therefore you pack some extra clothes (especially a change or two of underwear/socks/t-shirts). Having none of those prepped, the crews were pretty ripe after that third day when we went out to finally relieve them. Pulling Nuclear Alert in those next few weeks were extremely stressful, not knowing if that might be the time we are actually called upon to do our wartime jobs.
