When I last visited DAK on a Saturday in late April, there were a large number of people with bright t-shirts that stated something like "We helped build Pandora" and they were all steel workers from, I believe, Fort Lauderdale. I stopped a few of them while in Pandora and thanked them for their contribution. I then spent the next several awesome minutes listening to them point out all sorts of neat things, and tell cool stories about what I was looking at. My favorite was about fabricating and transporting the super steel beam they called the 'megaroot' on something like a 50 wheeled tractor trailer flatbed (I know nothing about trucking, or steel fabrication, so don't have the correct terms), in the middle of the night along Florida's roads, but not being allowed on overpasses due to the weight. And this 'megaroot, is somehow a major loadbearing component, even though it is not where one might expect it to be placed. I didn't understand the engineering, but loved listening to what they had to say, and appreciated their enthusiasm.It would be cool to actually see the workflow. The imagineers design all this, but it's all outsourced to other companies who actually specialize in making "animatronics" for theme parks. Obviously it's no small challenge to install and program it to work with the rest of the show.
