The FAA is allowing military style aircraft to fly through Southwestern Utah for training purposes.

The Iron County Sheriff’s Office reported Friday that after several calls from people, they learned of a low flying flight route through Utah from the Nellis Air Force base.

The route starts at the Black Ridge and runs north following I-15 to Beaver before it turns west and heads to Nevada.

The route is for training purposes only, according to officials.

The Nellis Air Force base also reports that it began an air-to-air combat training exercise Friday, known as “Red Flag 18-1.”

Southern Utah residents can expect to hear booms, shakes and rattling for the duration of the mock battle in the skies running through Feb. 16 and again March 9-23.
