In June 2015, it migrated to the northwest United States to join ADF Helicopters' large cherry drying S-58 fleet based in Brewster, Washington.

This is actually UH-34D Bureau Number 150227 painted as HUS-1L Bureau Number 144657. 144657 was assigned to VX-6 on Operation Deep Freeze in Antarctica. This a/c is now back in US Marine Corps markings with the correct Bureau Number of 150227 applied.

This inactive Sikorsky S-58T owned Helicopter Transportation Services was stored at Carp, ON prior to HTS selling its S-58 fleet to S. Korea in late 2019. It was delivered new to Humble Oil in May 1957 as N863 for offshore drilling support and operated by Rotor Aids from a large heliport in Grand Isle, LA. In Oct 1959, it was sold to Okanagan Helicopters in Canada in Oct. 1959 as CF-LWB and upgrade to a turbine S-58B/T 1971. It was owned by Helicsa in Spain (EC-CYJ) from 1976 until sold to the USA. Between 1991 and 2016, N47B, was operated by Air One, Air Crane and finally HTS.

This Sikorsky S-58T was flying scheduled passenger services between Manhattan's East 34th Street heliport (6N5) and JFK Airport in April 1984. After serving with the German Army and Navy since 1963, it was purchased by Sikorsky in 1973 for conversion to a S-58ET with a twin-turbine P&WC PT6T Twin Pac replacing the Wright R-1820 Cyclone. It flew with Air Greenland as OY-HBG, "Taliffak", between 1975 and 1982 until sold to the US. New York Helicopters (and its two sister companies) flew it 1982-1998. It was sold to St Louis Helicopters in Nov 1998 (for spare parts?) and canceled in July 1999.

Assigned to Naval Air Training Unit New Orleans when the photo was taken. This a/c was transferred to S. Vietnam, and eventually from there to Indonesia.
