Its a nice vid Vaq, surely.
With regard to precision flying I can think of a couple of assignments which might require a little more effort .. live-wire work on the electricty transmissions for one (if we're talking 500's) and I once witnessed an Erickson crew planting poles without ground-crew assistance alongside a road into prepared holes at the end of a 150ft line which, with the length of the pole probably brought the seat of the load closer to 200ft from the aircraft.
The Erickson team did have a ground crew but the fly boys were moving so fast that they were having difficulty catching-up. Watching the Skycrane driver manoeuvre the pole (without assistance) into the hole and then button the load to leave it resting upright was something else!
Re: the 500, she's a wonderful craft and I have to join Grumpy in declaring that I've come close to buying a 'D' model (a couple of times) and would probably have one already if I could just settle in one country long enough to be able to enjoy the thing! She's useless for pax (noisy and cramped) but for driving the skies on those days you simply want to fly and feel the bliss of man and machine working as one .. the 500 is hard to beat.
Back to Vaq's vid: There are some pretty unorthodox procedures taking place here but we'll let that slide for now. However, if it was my ship and someone performed a load-lift such as the one at 3:30 they would be greeted by a gentle slap to the back of the head once they landed! The difference, even with light loads, (in terms of impact upon the aircraft's dynamic systems) between taking up the slack and gradually introducing the load-weight to the aircraft .. and simply yanking the load off the ground .. is considerable.
Anyway, 500 - a great ship!
