It would seem that de Havilland had the benefit of actually having a Halford H-1 B turbojet to work with while Lockheed had only blueprint dimensions from which to design the P-80 around.
For the sake of the war effort, would it have been more practical or more effective to concentrate development at de Havilland, and/or have Lockheed build Vampires under license?
