Human external cargo
A couple years ago I was reading about one of the (California?) electric companies using single engine helicopters (MD500) with human external cargo (I think lifting guys to/from power transmission towers.
I just didn't get it... I don't see how any external cargo would survive an autorotation.
Of course, working on a live wire with a helicopter rotor overlapping the power line has some issues with engine failures, I'm sure.
Is there something I'm missing that makes it safer than I'm imagining?
