Though fog delayed the start, Civil Air Patrol and its crews sought crystal-clear photographs during a search and rescue exercise Saturday out of Lee Gilmer Memorial Airport in Gainesville. Four aircrafts from Gainesville, Peachtree-DeKalb, Lawrenceville and Athens took off Saturday morning to take pictures of targets during 90-minute missions. “They are training exercises for our crews for our main mission for whatever the state or federal government gives us,” said Lt. Col Richard Ivy, who served as the air operations branch director for the exercise.
