The Cornfield Bomber, the F-106 Delta Dart That Recovered Its Own Spin and Belly-Landed in Montana While Its Pilot Floated Down Under a Parachute

On February 2, 1970, a U.S. Air Force F-106 Delta Dart did something no aircraft is designed to do: it recovered from an uncontrolled flat spin after its pilot ejected, flew itself down through 15,000 feet of Montana winter sky, and made a survivable belly landing in a snow-covered cornfield near Big Sandy, Montana. When local farmers walked up to it, the engine was still running. The aircraft was repaired, returned to service, and flew for 17 more years.

What Was the F-106 Delta Dart?

The Convair F-106 Delta Dart was the premier air defense interceptor of the Cold War era. Designed in the early 1950s, its sole mission was to stop Soviet bombers before they reached American cities - nothing more, nothing less.

Powered by a single Pratt & Whitney J75 engine, the aircraft was capable of Mach 2.3 at altitude. Its distinctive delta wing, dart-shaped fuselage, and flanking nose intakes made it one of the most recognizable aircraft of its generation. It was fast, functional, and, by any measure, the finest pure interceptor the United States ever built.

The F-106 was flown by Air Defense Command, whose pilots sat five-minute alert in converted trailers next to runways in Montana, Minnesota, and Maine - waiting for a call from NORAD that, if it ever truly came, would mean the worst had already happened somewhere else.

The Flight: Captain Foust and the Flat Spin

Captain Gary Foust was a pilot out of Malmstrom Air Force Base near Great Falls, Montana. On the morning of February 2, 1970, he was airborne in tail number 58-0787 on a routine training mission - not on alert, just staying current.

Somewhere north of Havre, the aircraft entered a flat spin.

A flat spin is fundamentally different from a normal spin, and considerably more dangerous. In a normal spin, the nose pitches down and the aircraft rotates - uncomfortable, but recoverable with the right technique and enough altitude. In a flat spin, the aircraft rotates around its vertical axis in a nearly level attitude, with the relative wind coming up from below. The controls that would normally break a spin are now working against the pilot, and the altimeter unwinds at a rate that demands immediate action.

The F-106 had a reputation among pilots for being a thoroughbred at speed but difficult at low energy. In the wrong configuration, she could get into exactly this kind of trap. Foust worked the problem. He flew the aircraft as long as it could be flown.

The Ejection - and What Happened Next

With the ground rising and the spin unrecoverable, Foust made the correct decision. He pulled the handles and ejected.

The seat worked. He came down under his parachute in the Montana winter and survived.

His aircraft, now without a pilot, did something nobody expected. It recovered.

The precise mechanism remains a subject of discussion among those who study such cases. The departure of the ejection seat likely altered the aircraft’s weight and balance. The removal of the pilot’s control inputs may have eliminated whatever was sustaining the spin. The aerodynamics found their own equilibrium. Whatever the reason, the F-106 stopped spinning, the nose came down, and flying speed returned.

The aircraft then flew - not erratically, but in a wide, gradual descending spiral. The autopilot was partially engaged, or the trim was set in a configuration that produced a stable state. The J75 engine held a steady note. The delta wing found a groove and held it. The aircraft circled and descended through 15,000 feet of Montana air, taking its time.

There was nobody inside.

The Landing Near Big Sandy

Farmers in the fields near Big Sandy, Montana watched the aircraft come down. What they witnessed was the F-106 settle into a snow-covered cornfield - gear retracted, on its belly - at a speed the soft snow and flat terrain could absorb without catastrophic structural damage.

When the first people reached the aircraft, the engine was still running.

The Air Force dispatched a recovery crew. They shut down the engine, secured the aircraft, and assessed the damage. The fuselage was scratched, the underside scuffed, and the airframe bent in a few places. The engineers’ conclusion was as remarkable as the landing: the aircraft was repairable.

So they repaired it. Tail number 58-0787 went to depot maintenance, received new belly skin and structural repairs, and was returned to flying status.

Seventeen More Years in Service

The aircraft that belly-landed itself in a Montana cornfield went on to fly for 17 more years. Pilots who knew nothing of its history strapped into it and flew operational sorties, training missions, and alert cycles for more than a decade and a half after that February morning.

The mechanics and crew chiefs knew. The story moved through Air Defense Command squadrons the way good stories do - quietly, pilot to pilot, in alert shacks and officers’ clubs. The aircraft earned a nickname that followed it through the rest of its service life.

The Cornfield Bomber.

Not mockingly. With something closer to reverence.

Why This Story Matters

Captain Foust did everything right. He flew the aircraft until it could no longer be flown, then he got out. That is the correct decision in an unrecoverable spin at altitude. He had no way of knowing what the aircraft would do after ejection, and he owed it nothing more than his best effort and the will to survive. He walked away and flew again.

The aircraft simply refused to let the story end there.

For pilots, this incident sits in an uncomfortable space between aerodynamics and something harder to name. Every working aviator understands that an airplane is metal, rubber, wiring, and fuel - it does not want anything. The F-106 recovered because physics allowed it to, not because of intent. The analytical explanation is available, and it is sufficient.

And yet.

Where the Cornfield Bomber Is Today

When the Air Force retired the F-106 fleet in the 1980s, most airframes were converted to QF-106 drones - unmanned target aircraft used in live-fire missile tests, ultimately splashed into the ocean. It was an unglamorous end for an aircraft that had spent decades guarding American airspace.

Tail number 58-0787 was spared that fate.

It is on permanent display at the National Museum of the United States Air Force at Wright-Patterson Air Force Base in Dayton, Ohio, in the Cold War Gallery. There is no external marking on the aircraft to identify what happened in Montana. A visitor who doesn’t know the story will see an F-106 and move on.

A visitor who knows will see something else entirely.
