A routine training flight over Arizona in January 2023 took an unusual turn when a U.S. Air Force F-16D was struck by what was initially reported as an unidentified object, but now U.S. defense officials say was a small drone. Fox News confirmed that the incident, which occurred near Gila Bend, Arizona, on Jan. 19, 2023, was a routine training mission and was witnessed by the instructor pilot seated in the rear of the two-seat aircraft. According to a U.S. defense official, the pilot observed a "mostly white and orange object" collide with the left side of the aircraft canopy, the transparent covering over the cockpit. Initially, the object was thought to be a bird, a common hazard for aircraft. But after conducting checks during the flight and a detailed inspection upon landing at Tucson International Airport, the crew found "zero evidence" of a bird strike.

Artificial intelligence helped co-pilot a U-2 "Dragon Lady" spy plane during a test flight Tuesday, the first time artificial intelligence has been used in such a way aboard a US military aircraft. Mastering artificial intelligence or "AI" is increasingly seen as critical to the future of warfare and Air Force officials said Tuesday's training flight represented a major milestone. "The Air Force flew artificial intelligence as a working aircrew member onboard a military aircraft for the first time, December 15," the Air Force said in a statement, saying the flight signaled "a major leap forward for national defense in the digital age." The Artificial Intelligence algorithm, known as "ARTUµ," was developed by researchers at the Air Force's Air Combat Command U-2 Federal Laboratory. The AI system has been "trained ... to execute specific in-flight tasks that otherwise would be done by the pilot," the statement said.
