How can the FAA allow only one controller to be working? What if the controller gets sick, or has to go to the bathroom? I don't care how slow traffic may be at any given airport, at any given time, there should be more than one controller there. I have never been worried much about my safety when I fly,well except the first few times I flew an airbus and heard those strange hydraulic noises, but I got over that. (Settle down airbus pilots, I'm flying airbuses to LAX and LAS and over the next few days, and fly on them all the time)...
I might feel apprehensive now though, when I fly into the smaller airports at off hours. It looks like the blame for this tragedy is going to be spread around to more than just the pilots.
