The Cold War interceptor that once landed itself in a snowy Montana field

In short: Known affectionately as The Six, the Convair F-106 Delta Dart was the ultimate Cold War interceptor. Designed to defend American skies from bombers, it never saw combat, yet it achieved legendary status through its supersonic performance and a bizarre 1970 incident where an unpiloted jet landed itself intact.

The F-106 Delta Dart emerged from the United States Air Force's 1954 interceptor program, intended to be the definitive solution for all-weather defense. Originally developed as the F-102B, the aircraft was a significant evolution of the F-102 Delta Dagger. It featured a powerful Pratt & Whitney J75 turbojet engine and a clean, supersonic-optimized airframe that lacked external guns or bombs, housing its armament—including the nuclear-tipped AIR-2 Genie rocket—within an internal weapons bay.

Despite its advanced design, the program faced severe technical hurdles. Early flight tests in 1956 and 1957 revealed disappointing acceleration and speed, while the complex Hughes MA-1 fire-control system proved notoriously unreliable, requiring over 60 upgrades during its service life. The Air Force ultimately ordered only 350 of the 1,000 aircraft originally planned. Nevertheless, the F-106 became a staple of the Air Defense Command from 1959 until its gradual retirement in the 1980s, serving as the last specialist interceptor in the USAF inventory.

The aircraft's reputation for resilience was cemented on 2 February 1970, when a pilot ejected over Montana after his F-106 entered a flat spin. Without the pilot's weight, the aircraft stabilized and belly-landed in a snow-covered field with only minor damage. This 'Cornfield Bomber' was repaired and returned to service. Later, the F-106 found a second life in scientific research; one NASA-operated F-106B, dubbed the Lightning Strike Plane, was struck by lightning 714 times between 1980 and 1986, providing critical data on atmospheric electrical phenomena before the fleet was finally retired in 1998.

While the F-106 never engaged in combat, it remained a formidable performer. Pilots often favored it for its high-altitude maneuverability, and it frequently bested the F-4 Phantom II in training exercises. By the late 1980s, the arrival of the F-15 Eagle rendered the dedicated interceptor role obsolete, leading to the conversion of many surviving airframes into QF-106 target drones, which were used for testing until the late 1990s.
