Swingcraft

10km swing from LTA blimp

A blimp is steady in place high in the sky, tethered by 3 cables in a pyramid shape.

There are two more blimps, one at each of two "stations".

A rope from the main blimp serves as the swing.

A quadcopter at the bottom of the swing brings the rope to its initial position at one of the stations.

The packages or passengers are elevated by a motor on the ground and a pully on the station's blimp. The package is hitched on to the swing. Lets go of the station's cable and woo hoo! Off to the next station where it is caught, and slowly brought down to earth, or hitches onto the next swing.

See link about Ruwandan plane that hitches onto a catching cable.

       Improvement: only 1 permanent tethered blimp. No quadcopter. Package cable pulls a package glider by pulley all the way up to blimp. Then releases the glider for fast tethered free fall. When nearing destination uses tether for slowing down and stopping. Pulled back up with pulley and glides back down back to base.

       Another use: high altitude elevator for skydive or for ultralight gliding with Ram-air parafoils.   

       And still another: as an elevator to a high altitude restaurant.
