File photo - An airplane flies over a drone during the Polar Bear Plunge on Coney Island in the Brooklyn borough of New York Jan. 1, 2015. A video produced by the University of Dayton Research Institute shows in alarming detail what happens when a drone collides with a plane. The test, which mimicked a midair collision at 238 mph, launched a 2.1-pound DJI Phantom 2 quadcopter into the wing of a Mooney M20 aircraft. Experts from UDRI's Impact Physics group note that the drone did not shatter on impact, but tore open the wing's leading edge, damaging its main spar. "While the quadcopter broke apart, its energy and mass hung together to create significant damage to the wing," explained Kevin Poormon, group leader for impact physics at UDRI, in a statement.
