Lockheed T-33 US Air Force training aircraft. The T-33A was developed by modifying the P-80 jet which later became the “F-80 Shooting Star."  The fuselage of the P-80 was lengthened and a second seat was added which required the use of a larger engine. This design resulted in the T-33A.  Both propeller driven aircraft pilots and the new jet aircraft pilots were trained on the T-33A. The T-33A made its maiden flight in March of 1948.  Manufacture of this plane continued from 1948 to 1959.  The plane has served in the Air Forces of more than 30 countries becoming one of the most widely used trainers in history.
