This was actually supposed to be the last image in this essay, but I'm going to run it first as a way of an explanation--- I took this shot as I hopped off the helicopter and paused below the whirling blades to get a shot of the towering engine cowling. While I was shooting this, the rest of the crew that had been on the ground, boarded the helicopter, and when I was clear, they took off! This was not part of my plan! I never got a chance to take down names, or get the story straight on who these folks were. So this essay, while visually entertaining (I hope), is woefully inadequate in terms of credit given or knowledge imparted. So, when you're done looking at the pictures, if you want, you can ask for a full refund.
