The following pictures were taken at Nellis Air Force Base, Nevada, on Jan. 31, 2013.
The B-52 has eight turbojet engines, each capable of producing 17,000 pounds of thrust, with a top speed of 650 miles per hour. They leave long white contrails over Nevada during the training mission.
The B-52 is entering its sixth decade of service. Nevertheless it remains the backbone of the Air Force bomber fleet.
