Cause this is one bad ass motherfucker
Why did he fly 52 missions? Because he wanted to kill Nazis that bad.
Lieutenant Colonel Robert "Rosie" Rosenthal (June 11, 1917 – April 20, 2007) was an American lawyer and bomber pilot. A highly decorated officer of the Eighth Air Force of the United States Army Air Forces in World War II, he received sixteen awards including the Distinguished Service Cross for "extraordinary heroism in connection with military operations against the enemy," the Silver Star (with oak leaf cluster) for "gallantry in action," the Distinguished Flying Cross (with oak leaf cluster) for "heroism or extraordinary achievement during aerial flight", the Air Medal (with seven clusters) and the Purple Heart (with cluster), as well as the Distinguished Flying Cross from Great Britain and the Croix de Guerre from France. In March 1944, Rosenthal's crew, nicknamed "Rosie's Riveters", with their B-17F, serial number 42-30758 bearing the same name, completed their 25-mission combat tour and returned to the United States, but Rosenthal extended his tour, eventually flying a total of 52 missions.
