Yeah, what's really interesting is a statement made from 31:24 to 31:43 by Willis Hawkins: "The L-133 evolved in the way it did mostly because we were not very convinced that the right way of making a supersonic airplane was with swept wings."This documentary features Sherman Mullin and Willis Hawkins, former president and senior vice president of Lockheed's Skunk Works.It tells the story of the development of the P-38, the L-133 and its L-1000 engine, subsequent founding of the Skunk Works and later development of the P-80, F-104, U-2, SR-71, Have Blue, F-117, F-22 and F-35. With this much history to cover, the best bits are when Mullin and Hawkins are reminiscing.
