According to the report, U-2 designers came up against two central problems in developing the plane: fuel capacity and weight. To solve these dilemmas, the tail, wings, and landing gear were constructed unlike any other U.S. military aircraft.
The tail was attached to the main body with just three tension bolts to save weight; and the wings were ultra long, thin, and narrow. The landing gear was also lightweight with a set of wheels in the front and the rear of the aircraft. While on the ground, pogo sticks were used to prop up the U-2's wings. Pictured here is the U-2 landing gear with the wing pogos.
