The Cornfield Bomber and the F-106 Delta Dart that landed itself in a Montana field

On February 2, 1970, a Convair F-106 Delta Dart recovered from a flat spin—a maneuver considered unrecoverable—and landed itself in a snow-covered Montana wheat field with no pilot aboard. The aircraft, which became known as the Cornfield Bomber, was recovered, repaired, returned to service, and now sits in the National Museum of the United States Air Force at Wright-Patterson Air Force Base.

What Was the F-106 Delta Dart?

The Convair F-106 Delta Dart was one of the fastest interceptors ever built for the United States Air Force. A single-engine, single-seat fighter designed to scramble against Soviet bombers, it could reach Mach 2.3 and weighed 26,000 pounds. Its delta-wing configuration made it an effective high-altitude interceptor throughout the Cold War era.

What Happened Over Montana?

Captain Gary Foust was flying out of Malmstrom Air Force Base in Montana as part of a four-ship formation conducting practice intercepts and air combat maneuvering at altitude. During one engagement, Foust’s aircraft departed controlled flight and entered a flat spin.

A flat spin is one of the most dangerous situations in aviation. The aircraft rotates horizontally—like a frisbee falling—rather than nosing down. It descends at thousands of feet per minute with little to no pilot input having any effect. In 1970, a flat spin in an F-106 was considered unrecoverable by every manual, instructor, and pilot who had encountered one.

Foust attempted recovery procedures, working the controls through every technique available. Nothing worked. At approximately 15,000 feet, with the ground approaching rapidly and no improvement in the aircraft’s attitude, he ejected.

How Did the Aircraft Recover Itself?

When Captain Foust’s Martin-Baker ejection seat fired, it triggered a chain of events no engineer had predicted:

1. The ejection shifted the aircraft’s center of gravity — removing the pilot and heavy ejection seat changed the weight distribution
2. The drag chute deployed automatically — standard procedure when the canopy separated, adding stabilizing drag to the tail
3. The engine continued running at idle — providing just enough thrust to maintain controlled airflow

These three factors combined to do what Foust could not: the flat spin slowed, the nose dropped slightly, and the F-106 transitioned into a gentle, wings-level descent. The aircraft that a trained fighter pilot couldn’t recover had recovered itself the moment the pilot departed.

Where Did the Cornfield Bomber Land?

The pilotless F-106 descended through clouds, crossed farmland east of Big Sandy, Montana, and touched down gear-up in a snow-covered wheat field. It slid across the snow and frozen stubble and came to rest virtually undamaged. The engine was still running at idle when the first responders arrived.

A local sheriff’s deputy who drove out expecting wreckage and a crater instead found a complete aircraft sitting in the snow with its engine humming.

What Happened to the Aircraft Afterward?

The Air Force recovered the F-106, transported it to a depot, and repaired it. The work was relatively minor: new belly skin where it had slid on the ground and some engine and airframe maintenance. The aircraft was returned to active service and flew operationally for years afterward.

It eventually was retired to the National Museum of the United States Air Force at Wright-Patterson Air Force Base in Dayton, Ohio, where it remains on display today with a plaque recounting the full story.

The name “Cornfield Bomber” stuck despite two inaccuracies—it landed in a wheat field, and it never dropped a bomb in its life.

Why Did the Self-Recovery Work?

The Cornfield Bomber incident sits at the intersection of engineering and luck. Every one of these factors had to align:

• The weight change from ejection had to be sufficient to alter the spin dynamics
• The drag chute had to deploy and remain intact
• The engine had to keep running at idle
• The terrain below had to be flat and unobstructed
• The snow had to cushion the gear-up belly landing

If any single factor had gone differently, this would be an unremarkable crash report rather than one of aviation’s most enduring stories.

What Happened to Captain Foust?

Captain Gary Foust landed safely under his parachute, suffered only minor injuries from the cold and ejection forces, and continued to a full military career. He reportedly had mixed feelings about the event—grateful for survival, but aware that his aircraft had demonstrated better recovery skills than he had in front of the entire squadron.

Key Takeaways

• The Cornfield Bomber is a real, documented event — an F-106 Delta Dart recovered from a flat spin and landed itself without a pilot on February 2, 1970
• The ejection itself caused the recovery — the shift in center of gravity and drag chute deployment stabilized what was considered an unrecoverable spin
• The aircraft was repaired and returned to service — suffering only minor belly damage from the gear-up landing on snow
• The F-106 is preserved at Wright-Patterson AFB — visitors can see the actual Cornfield Bomber at the National Museum of the United States Air Force
• The incident demonstrated that aerodynamic behavior can defy established doctrine — the “unrecoverable” classification had to be reconsidered in light of this evidence
