Kenneth Thompson, 576th Aerospace Maintenance and Regeneration Squadron aircraft mechanic, fastens a screw on top of an A-10A Thunderbolt on Davis-Monthan Air Force Base, Ariz., Jan. 23, 2013. After the 309th Aerospace Maintenance and Regeneration Group is done repairing the aircraft, it will take approximately one year to convert the aircraft into a drone used to collect data on storms.
