I gave this cute little helicopter the nickname, the bumblebee, for obvious reasons. I believe it was engaged in some kind of infrared or 3D survey of the island, the black box on the front being the most obvious of many bits of equipment in the little aircraft. Whatever it was doing, the bumblebee buzzed back and forth for several days, methodically working its way up and down the slopes, stopping only to refuel every now and then.
