This is an album of photos I have taken of a KC-135 Stratotanker. The KC-135 was developed from the Boeing 767 airframe and is used for aerial refueling operations using a boom located at the aft of the aircraft to fuel planes trailing the tanker. The aircraft shown here is operated by the 126th Air Refueling Wing of the Illinois Air National Guard. These images were taken at the 2019 Spirit of St. Louis Air Show.
