Have you ever seen the largest Red Flag exercise in the United States Air Force? Do you know how fighter planes refuel in the air during the Red Flag exercise? And how do fighter pilots from various countries rescue their companions? And how to carry out the plan to simulate bombing during the Red Flag exercise? You can find the answer in the new movie "Flying Warriors: red Flag exercise" released at the Imax Theater. * * the most realistic simulation exercise, the Red Flag exercise, is the first large-scale integrated air combat exercise in the world. it is also the most well-known, respected and realistic simulation exercise that pilots have ever participated in. The Red Flag exercise was founded by the United States Air Force in 1975 to improve the air combat skills of its pilots because it was shown in the Vietnam War that most of the damage was lost by inexperienced pilots in their first few missions. Under the pressure of combat, there is no way to train them on how to survive in air combat. This concept was proposed by Colonel Richard Suter and realized by General Robert Dixon. In the extremely lifelike training environment of the red flag exercise, rookie pilots gradually learn how to survive on the battlefield. The Red Flag exercise is held at Nellis Air Force Base every year.
