The "Cornfield Bomber" is the nickname given to a Convair F-106 Delta Dart of the United States Air Force's 71st Fighter-Interceptor Squadron which made an unpiloted landing in a farmer's field in Montana in 1970.

During a routine training flight conducting aerial combat maneuvers on February 2, 1970, the aircraft entered a flat spin.

"[2] From his parachute, Foust watched incredulously as the now-pilotless aircraft descended and skidded to a halt in a farmer's field near Big Sandy, Montana.

[3] The sheriff, having contacted the air base, was informed that he should simply allow the jet to run out of fuel, which occurred one hour and 45 minutes later without further incident.

[2] A recovery crew from McClellan Air Force Base arrived on the scene and began to dismantle the aircraft, removing its wings for transport aboard a railroad flat car.
