In the mid-1950s AAHS member Warren Bodie with the assistance of Ms. Jennie Reeves (custodian of the Wright Field still photo files), Peter M. Bowers, William T. Larkins and John Sloan compiled an index of the aircraft tail numbers (P-number) for McCook Field (and later Wright Field).  The period covered was 1918 through 1930.  P-numbers were assigned to aircraft used in engineering and research evaluations during this period. Even at this date no one is sure what the “P” represented – plane, project or procurement.  Aviation historians and photograph collectors have long noted these identifier numbers painted on the rudders of various aircraft. The original list was published in Vol. 1, No. 4, of the AAHS Journal (October-December 1956). This information has been updated using a number of published references including significant data provided by Drew Taylor derived directly from the airplane records by month for both engineering divisions at McCook and Wright Fields, and further supplemented by Robert Casari.

The following is an updated listing of the McCook Field P-numbers. It includes additional aircraft that were not in the original listing, as well as information regarding the engines installed (in many cases including their Air Service number).  A notes column has been added that contains additional information about the aircraft.
