MTSU assistant professor Kevin Corns, right, aerospace unmanned aircraft systems director, introduces university alumnus and Tennessee State Parks Chief Ranger Shane Petty to his class earlier this year in BAS. Petty spent three hours detailing a mystery of a missing hiker at Cummins Falls State Park near Cookeville, Tenn. Though the missing hiker’s remains were discovered March 29, the class will still fly drones and map the park for authorities on Friday, April 1, as part of a capstone project. (MTSU photo by J.
