According to the web sites, there was a USAF ground crew waiting on it. They also had volunteers assist. I had the same thoughts. You don't land an aircraft like that without ground crew on a non-USAF landing site. I'm sure that they arrived earlier. What I want to see is if they can take off on an 8k feet runway. I'm sure that they can, otherwise they wouldn't have landed there. Probably won't have a lot of fuel and will refuel once airborne.
