A Boeing KC-97L <i>Stratofreighter</i> (s/n 52-2630) at the National Museum of the United States Air Force. The USAF retired its last C/KC-97 in 1973, but others remained in use with the Air Force Reserve and Air National Guard as tankers or search and rescue aircraft. During "Operation Creek Party", which started in 1967 and lasted for 10 years, U.S. Air National Guard and U.S. Air Force Reserve tankers supported active duty USAF and NATO units in Europe. The aircraft on display, flown by the 160th Air Refueling Group of the Ohio Air National Guard, participated in this operation, and on 7 June 1973, the mayor of Zeppelinheim, a town near Rhein-Main Air Base in West Germany (today part of Frankfurt International Airport), christened this aircraft in his town's honour. In 1977 Zeppelinheim became part of the city of Neu-Isenburg. The KC-97L <i>Zeppelinheim</i> was flown to the USAF museum in August 1976.
