As for using ladders, have you ever seen what happens when a guy working from a bucket truck loses his isolation from the ground? It's a body deep-fry. The only way to do this type of maintenance efficently is via chopper. The lines are too powerful, too high up, and too remote to be done from the ground. It would cost at least twice as much to do the same operation from the ground. The cost is not as much as you might think. They lease the helicopter and train their own technician. The only non-fixed costs are fuel.
