Very few aircraft in the history of aviation have been able to reverse the reputation of a loser throughout their service life, Thunderchief among them. The aircraft was designed by Fairchild Hiller Corporation's Ripablik Aviation Division. Corrected his reputation "Thunderchief" during the first four years of the Vietnam War. The Phantom rightfully became a symbol of the "dirty" war, but in the early years of the conflict, 70% of the bombing of North Vietnam was carried out by bombers with the Ripablik brand.
