The Zippy Twins.

OK, a little orientation before you begin. The cemetery is at the end of my yard in front of my house. The camera is loacated in the driveway. Zippy flies past the camera and hits a corner and hangs a left. He then shoots about 20 feet and hits another corner, making another left turn. He flies back across the side yard into the carport, hitting the ceiling fan motor in what is essentially another left turn. Here's where the fun starts. He hits the next corner and makes a right turn to cross back into the front yard, down the straight-away to the corner. He zips around it, making a 180 and begins his trek again, As he comes toward the camera, he and his twin pass each other in the front yard. The camera stays on Twin #2 as he swings around the 180 degree turn and flies to the corner we saw Zippy #1 fly around first. The Zippys are fun!
