U.S. Air force and local civilian pilots gather for Joint Base Charleston’s first Mid-Air Collision Avoidance event in the back of a C-17 Globemaster III Nov. 5, 2016. The MACA program is designed to promote aviation safety between military and civilian pilots who share the local airspace. Sharing the mission of JB Charleston with community civilian pilots offers a better understanding of why specific procedures are put in place. The event gives pilots, military and civilian, a forum to discuss flying and aviation safety.
