An instructor pilot for the 80th Flying Training Wing asks NATO Secretary General Jens Stoltenberg a question at Sheppard Air Force Base, Texas, April 6, 2018. The instructor pilot asked Stoltenberg about the future of pilot training now that artificial intelligence is a possible alternative. Stoltenberg responded that there will always be need of human pilots, but in the future they will probably be working together with unmanned aircraft systems as well.
