In many ways, the Douglas "Invader" aircraft is truly great. A powerful, aerodynamically clean airplane looks very aesthetically pleasing. His combat career, even only in the United States Air Force, is truly unique. It began at the end of World War II and ended in Vietnam. The plane took part in a mass of small armed conflicts. Invader aircraft are in service with many countries of the world, the last V-26 were withdrawn from service in the 80s. "Invaders" flew a lot on the "citizen," which was largely facilitated by numerous modifications of this aircraft.
