Skycrane

The SHEDS exercise, conducted by American Export Isbrandtsen and Sikorsky in 1967, demonstrated that skycranes can unload containers, within the load limits of the helicopters, from a ship’s deck in weather which makes surface operations impossible.

Bad weather, damaged multileg slings, and limited weekend availability for National Guard skycranes caused planning problems.

For the cost of those exploits, Bass could easily rent a couple of skycranes and airlift Hueco Tank’s famous Mushroom Boulder to Louisiana.

Helicopter skycranes offer several advantages over conventional cranes.[…]Large skycranes are often used in the lumber business to lift large trees out of terrain that is too rugged for a ground-based vehicle.

Perhaps a more important question is whether the large amount of money associated with establishing and then continuing to maintain firebreaks might have been better spent on other options for fighting fires such as more skycranes, rapid response units or other kinds of equipment.

Only two skycranes came in hauling tractors and we aren’t allowed to get rides on them.

As the [Perseverance Rover] descent stage levels out and slows to its final descent speed of about 1.7 miles per hour (2.7 kilometers per hour), it initiates the “skycrane” maneuver.
