There are several things going on here. Mostly, it's Bill and Marquis painting the UH-18 (the Yellow Dragon) and Jason Kuehn getting his UH-13p lift engine running. Jason's also working on his trailer.

If you pay attention, you can see that Jason's lift engine is running for some of this. Even at full lift in a couple of the shots. The bag is full, and that's about the only way you can tell. These photos were taken by a digital camera, and I'm amazed that the "shutter speed" is that fast. It's not shutter speed, of course, since it's all electronic. But the camera technology is a lot further than I'd thought. The best you can see is when it's at full lift the engine mounts are sharp lines and the prop is slightly blurry.

	Here it's running, as on several shots on the way down here.
	Here it's running too, and I can't tell on the web version of the picture. The high quality one shows a 2 or 3 pixel blurring of the blades.
	This one you can sort of tell.
