U.S. Air Force Senior Airman Mark Murray, 849th Aircraft Maintenace Squadron remotely piloted aircraft communications technician, unfastens a bolt connecting a ground data terminal unit to a platform, Feb. 7. After unbolting the GDT from its shipping platform, it’s lifted by a crane, and installed on a tower to reduce potential line-of-sight deficiencies for RPAs.
