At approximately 8:30 p.m. on March 9, 2021, Greensboro ATCT (GSO) member Noah Walker was working the approaches into Greensboro, N.C., from the tower cab, as the positions were combined and the radar position was moved to the tower. Walker was lining up a Lifeguard aircraft to the final for Runway 14. Just before he instructed the pilot to contact the tower, he noticed lights that appeared to be another aircraft in conflict. Walker asked the tower controller if he was talking to an aircraft, but the controller confirmed he was not. Walker determined it was a drone flying near the arrival corridor for runway 14. Since the controllers could not predict the erratic behavior of this very large drone, they had no choice but to suspend operations at GSO until they could be reasonably sure the drone no longer presented a threat. Walker’s actions on this night prevented a collision and ensured the safety of the users in the airspace. NATCA is proud to recognize his professionalism and skill to identify the hazard even though it did not appear on radar. It led one pilot to comment on frequency, “Thanks for looking out for us.” Walker will be honored on June 17 in New Orleans with the Archie League Medal of Safety Award for the Southern Region.
