Battle of the X-Planes

Two aviation giants, Lockheed Martin and Boeing, compete to build the next generation fighter jet and win the largest US government contract ever awarded, estimated at one trillion dollars. For over five years, with unprecedented access from the Pentagon, NOVA followed the trials and tribulations of this neck-and-neck design war. The programme gives a unique perspective on every phase of the competition, from design and assembly through to the thrilling test flights that eventually led to the triumphant victory of Lockheed's aircraft.
