Something that was, and no longer is... Looks like an American transport helicopter of some sort; I've seen it before, but I can't place it. Yet...

EDIT: Hah, found it. It's a Sikorsky S-56.

Ooops, yes. Ch-37

Had to carry a case of motor oil.

The Army version, then, the H-37?

At the time of delivery, the CH-37 was the largest helicopter in the Western world, and it was Sikorsky's first twin-engined helicopter. Two Pratt & Whitney Double Wasps were mounted in outboard pods that also contained the retractable landing gear. This left the fuselage free for cargo, which could be loaded and unloaded through large clamshell doors in the nose. The single main rotor was five-bladed, and designed to function with one blade shot away in combat.


The CH-37 was one of the last heavy helicopters to use piston engines, which were larger, heavier and less powerful than the turboshafts subsequently employed. This accounted for the type's fairly short service life, all being withdrawn from service by the late 1960s, replaced in Army service by the CH-54 Tarhe.

Four CH-37Bs were deployed to Vietnam in 1963 to assist in the recovery of downed US aircraft. They were very successful at this role, recovering over $7.5 million dollars' worth of equipment, some of which was recovered from behind enemy lines.
