Well, it's not quite that bad. The guys on the tower are the ones with
control over the load which is in equilibrium. All you have to do is push
or pull the load up or down or sideways and that's what it does. It's
pretty easy - assuming of course that the helo isn't gyrating a lot.
A potential problem is that the slung load will build up a static
charge due to the large amount of air blowing by it. If you don't dissipate
the
charge, you'll get a real jolt. A local guy grabbed the load without
discharging it and it knocked him out. Maybe it was his head hitting the tower
but the end result was the same.
Fifteen or 20 years ago a small one rented for $450 an hour. I'll
guarantee it's lots more now.
