I was all set to take some bird images this morning but then this came along and the birds left in a hurry. There is a high power electric line that is near our home here in Southeast Missouri, USA. They use this helicopter and tree trimmer to keep the trees trimmed away from the high power lines. They have permission from a neighbor to operate out of his pasture. They haul all of the parts in on a truck and put them together then the helicopter lands and they attach the trimmer to it. The pilot then takes off and engages the 10 ~ 24 inch blades on the trimmer and flies along the right of way trimming the limbs from the trees. This thing can cut a six inch limb off like it was a twig. When they land for fuel they disengage the cutters and slowly lay the whole thing on the ground while flying slowly forward and down. Very interesting to watch but the birds sure do not like it!!
