Seabat over Illinois
Here we see a Sikorsky S-58JT, registry# N4247V, owned by aviation firm Midwest Truxton in Cook County, Illinois.
The airframe, SN 58-1547, was ordered as a U.S. Navy HSS-1N Seabat, BuNo 150754 (MSN 58-1547) in 1962 but was instead completed to CH-34C standard for West German Army (Heer), where she served as QB+483, then QW+404, and finally 8070 for the next two decades of the Cold War.
Sold on the civilian market in 1983, she first flew as N83829, then OB-T-1008, then N4247V, her current number, still going strong after 56 years.
For the record, the U.S. Navy got out of the Seabat/UH-34 business in 1973, while on the way out of Vietnam.
