An Euro-NATO Joint Jet Pilot Training Program student pilot uses red and blue planes to show aircraft formation types at Sheppard Air Force Base, Texas, Dec. 10, 2019. The red plane represents the "bandit plane" which basically means the "bad" plane, while the blue plane represents the ENJJPT pilot. Using the red and blue planes, the instructor can show different scenarios and where the ENJJPT pilots should be in each situation. (U.S. Air Force photo by Senior Airman Pedro Tenorio)
