From The Archives: Sikorsky S-58 Transfers 103 Tons In Six Hours

We reported on a Sikorsky S-58 helicopter that was seen in San Diego performing a lifting job to move 100 tons of heating and ventilating equipment on a 13-acre. roof of a missile plant being built for Convair Astronautics Divisions of General Dynamics Corp. The job required 70 quarter-mile flights and was completed in six hours. 

The airlift consisted of picking up cargo stockpiled on a parking lot, carrying it to the factory, and lowering it while a crew of riggers hand-jockeyed the units into precise position. 

See the images, including one where a spotter in the doorway of the helicopter directs the helicopter pilot in a disengaging maneuver and one showing the helicopter carrying one crate weighing 3,400 lb. 

See the picture story on pages 94 and 95 of the Feb 17, 1958 issue of Aviation Week.
