     One of the first aircraft built by the newly formed McDonnell Aircraft Corporation, the XP-67 was developed from an earlier design study for a long-range fighter. This earlier design, though rejected by the Army Air Corps, showed sufficient innovation to warrant the allocation of development funds. McDonnell came up with a new design and on July 29, 1941 this project received the designation of XP-67 and two prototypes were ordered.
    The McDonnell design team created an interesting looking aircraft by using airfoils whenever possible, forming a design that seems to have the various components merge together. The XP-67 was fitted with a pressurized cabin and powered by two Continental XI-1430 engines equipped with GE D-2 Turbo-Superchargers driving four-bladed airscrews. The original armament was to be six .50 machine guns and four 20mm cannon later changed to six 37mm M-4 cannon though studies were made to equip the aircraft with a 75mm cannon.
    Ground trials began in early December but halted on the 8th when fires started in both nacelles during an engine run-up. The problem was identified as a malfunction of the exhaust manifold slip rings and delayed the flight trials for nearly a month. Flight testing commenced on January 6, 1944 but the first flight was aborted due to engine problems. Various modification were made and flight testing resumed but was once again halted when on the fourth flight the engines were overspeeded resulting in the bearings burning themselves out.
    Due to parts being unavailable the aircraft was returned to McDonnell where modifications to the tail plane were undertaken. It wasn't until March 23, 1944 that flight testing resumed. Despite repeated modifications the aircraft suffered from generally poor performance and dangerous handling characteristics. On September 6th, 1944 the prototype was severely damaged by fire and it was decided that the second prototype would require too much time to complete and the development contract was cancelled. -
