I was deployed to Incirlik AB, Turkey for Operation Northern Watch (again). We'd finished up for the day and was just getting back to tent city. I think I had just thrown my gear on my rack and grabbed a cold one when my buddy turned on the TV. The first tower had just been hit and our first response was "Huh, what movie is this?". Shortly after the second tower was hit, the siren went off on base.
We scrambled back into work and got the jets ready, but the call never came out to launch. The replacement unit for us was in-route and they ended up spending a week at Ramstein. I ended up staying in-country for quite a bit longer...
