Photographed from the rear, this Boeing KC-97 Stratotanker displays the flying boom refueling system that allowed it to transfer fuel to jet bombers and fighters in mid-air. Operating from air bases across the country, including desert installations in the Southwest, the KC-97 extended the range and striking power of the U.S. Air Force's jet fleet throughout the 1950s and into the 1960s, forming a critical link in Strategic Air Command's global reach.
