TUCSON, Ariz. -- Authorities say it was an F-16 from Luke Air Force Base in Glendale that broke the sound barrier and rattled some windows in the Tucson area.
Luke officials say its 425th fighter squadron was flying F-16 training missions in the Sells area around 7:45 p.m. Wednesday and one of the jets ``went supersonic just northwest of Kitt Peak'' near Tucson.
Base officials add the altitude at which the aircraft broke the sound barrier was legal for supersonic flight in the area.
The say F-16s in the mission were using flight paths and corridors around the Barry M. Goldwater Air Force Range in southwestern Arizona.
The Arizona Daily Star says hundreds of calls came in to Tucson-area 911 dispatchers around 8 p.m. Wednesday.
There were no reports of any damage.
