detached and the capsule was filled with seawater. The extra weight was too much for the H-34 and the capsule, Liberty Bell 7, was emergency released and sank in deep water, remaining on the ocean floor until 1999. Sikorsky set up a production line in 1970 to remanufacture existing S-58 aircraft into the S-58T configuration, replacing the R-1820 engine with a pair of Pratt & Whitney Canada PT6T-3 Twin-Pac turboshafts; Sikorsky obtained a Federal Aviation Administration type certificate for the conversion in April 1971. The conversion enhanced safety, allowing the aircraft to continue flight after an engine failure, and greatly improved its hot and high performance; whereas the R-1820 could only provide full power up to an altitude of , the paired PT-6s provide full power up to , and an S-58T can fly at maximum gross weight up to . The type certificate for the S-58T was sold to California Helicopter International in 1981. In the late 1980s and early 1990s, S-58T helicopters were operated by New York Helicopters in scheduled passenger airline service between JFK International Airport and East 34th Street Heliport, New York. In the early 1970s, Orlando Helicopter Airways developed a novel civil conversion of the S-55/H-19, the Heli-Camper, a campervan-like conversion—featuring a built-in mini-kitchen and sleeping accommodations for four. Later in that decade, Orlando developed a larger version based on the S-58, and participated in a joint effort with popular American recreational vehicle (RV) manufacturer Winnebago Industries to market both aircraft as the Winnebago Heli-Home. The S-58 version featured a larger kitchenette, sleeping accommodations for six, a minibar, and an entertainment system; optional floats were offered for amphibious operations. The aircraft were featured in several American popular magazines and reportedly drew large crowds at RV shows and dealerships, but their high purchase price together with rising 1970s fuel prices resulted in very limited sales; production is not well documented, but is estimated at only six or seven of the S-55 and S-58 versions combined.
