A heavy-lift helicopter capable of transporting payloads of 20 to 30 tons is one of several advanced helicopter designs being developed by The Boeing Co.'s Vertol Division. The three-engine, tandem-rotor copter would be able to cruise at 130 knots with an external payload while meeting all military operational requirements. Boeing is conducting extensive wind-tunnel tests and systems-analysis studies of the helicopter.

Five high speed rotorcraft configurations are considered: the high speed helicopter, compound helicopter, ABC, tilt rotor and the X wing. The technology requirements and the recommended actions are discussed.

What bugs me is that Boeing closed the door on flying cranes just because the HLH contract was cancelled.

If the idea had so much potential as these beautiful paintings suggest, why didn't they try to push the concept forward on the civilian market all the same?

I think this is an example of a number of potential technologies where the market never quite materializes.  Sort of a chicken-and-egg problem in that you can't build systems that have no market, but the market doesn't emerge without the systems to enable it.  For example, it's hard to convince the logging industry to invest in giant helicopters that don't exist, while the giant helicopter builders would be reluctant to invest without orders on the table.  Catch-22.

Sikorsky sold the manufacturing rights to the S-64 Skycrane to Erickson Air-Crane of Portland, Oregon in 1992. Erickson refurbishes old S-64 helicopters and manufactures new S-64 Aircrane helicopters. Erickson Air-Crane is also the largest operator of S-64 helicopters.

I wonder how many units Boeing or Sikorsky would need to sell of skycranes to make it worth their while as opposed to a niche business.

I haven't seen skycrane helicopters used to unload and transport ISO Intemodal containers at sea or at cargo terminals. I could see the military being interested in doing this if they need to offload cargo at destinations with no local infrastructure, but commercial operations usually use ports with cargo handling equipment that can offload ISO Intermodal containers onto trucks or railroad cars. Seems to me that skycranes would be an expensive way to transport ISO Intermodal containers and cause noise and airspace congestion issues that would make them unpopular with civilian populations.
