Many kinds of construction work, now handicapped by lack of roads and bridges,could be done easily by the flying crane. The crane helicopter might also prove useful inspeeding delivery of goods between factories and such transportation centers as airports,piers, railroad yards and truck depots. It might carry detachable cargo pods. . . . "An entirely new cockpit design will givethe pilot a range of vision believed unpre- cedented in any other aircraft. A glass-enclosedcabin will provide unobstructed vision in any direction. The pilot's seat will swivel to therear so that he may obtain a clear view of loading and unloading operations. In the rear-ward facing position, he will operate a separate set of controls and will look almost directlydown the hoist to the cargo. . . . "Main and tail rotor heads, blades, transmis-sion parts and drive shafts of the S-56 are incorporated." S-58 Well over a thousand of theseaircraft have now been supplied to com- S-56 This very large helicopter is usedby the U.S. Army (H-37) and Marines (HR2S). It can carry 36 fully equippedtroops, with an alternative cargo capacity of 1,325 cu ft. Loading and unloading canbe achieved through clamshell doors in the nose, a cabin floor hatch or cargo doorlocated on the right side of the fuselage. Vehicles can be driven up the loading rampinto the cabin, which can accommodate two jeeps. A traversing electric hoist witha 2,000-lb capacity permits easy hoisting of cargo into the cabin and placing indesired position. Automatic stabilization equipment, semi-automatic blade-foldingequipment, retractable landing gear, and a 10,000 lb-capacity automatic touchdown- FLIGHT, 15 May 1959 697 release cargo sling to carry external loads are provided as desired.
