An A-10C Thunderbolt II from Davis-Monthan Air Force Base unintentionally released a rocket that exploded about 60 miles northeast of Tucson Thursday, officials said.
There were no injuries, damages or fires reported after the single M-156 rocket exploded around 10:40 a.m., base officials confirmed. The plane was involved in a routine training mission in the uninhabited desert of the Jackal Military Operations Area.
The area is "not designated for munitions release," officials said. An incident investigation is ongoing.
The aircraft is assigned to the 354th Fighter Squadron from the 355th Wing at Davis-Monthan.
