In 1942, aviation pioneer and company founder Glenn L. Martin was called before the Senate Special Committee to Investigate the National Defense Program, (or also known as the "Truman Committee"), which was investigating defense contracting abuses. Senator Harry S Truman of Missouri, the committee chairman (and future Vice President and 33rd President of the United States in 1945-1952), asked Martin why the B-26 had problems. Martin responded that the wings were too short. Senator Truman curtly asked why the wings had not been changed. When Martin replied that the plans were too close to completion, and his company already had the contract, Truman's testy response was quick and to the point: In that case, the contract would be canceled. Martin corrected the wings. (By February 1943, the newest model aircraft, the B-26B-10, had an additional of wingspan, plus uprated engines, more armor and larger guns.)
