We were told that yes, it had been done on the Peninsula. It worked until the wind came up. It was spendy. It didn't become common and had to have nice big logs to yard in order to make any money. We know what happened to that. Then there was the deadly helistat, which was deadly and a weird idea to begin with.
I worked 3 or 4 months for Evergreen Helicopters on one of their logging operations. (Anyone remember them?) No doubt the most dangerous job I've ever had. I'm trying to imagine how working around the Helistat would compare, if it worked. Presumably heavier loads, but more leisurely. A turn with the Sikorsky S-64s Evergreen flew took on the order of five minutes and weighed up to 20,000 (*) pounds. I worked on the landing and it took some scrambling to untangle the jack-strawed pile of logs that had been dropped, untangle and retrieve the chokers, coil and bundle them and hook them to the little 'copter that was also buzzing around who would return them to the choker setters. And get it done before the next turn dropped so there wasn't an even bigger mess on the landing.
* In a few spots where we worked the landing was on a hillside above the cut and the helicopter's approach was nearly vertical. The first thing we would see was the blades rising from below. You could get a sense of how big a load was on by how much the blades curved up at the tips. Six 36' long blades. They bent a couple due to overloads while I was with them.
