This collection consists of a series of 68 "Field Reports" completed by Frank T. Coffyn logging flight activities of Wright (Brothers) aircraft, for the period from May 5, 1910, through February 24, 1911. (One report is for March 26, 1917, and appears to list Coffyn's flights for that day.) The reports were completed on preprinted forms with columns for "Machine Number, Operator [pilot]," "Passenger," "Time of Flight," "Wind Direction," "Wind Velocity," "Length of Flight (Time and Distance)," and "Remarks." Spaces were also provided for Date, Gasoline Used, and Oil Used, and a signature. Fifty-six of the reports are signed by Frank Coffyn; the remaining sixteen appear to be in Coffyn's handwriting. Most are carbon copies. The reports cover flights made at Huffman Prairie, Ohio; Indianapolis, Indiana; Montreal, Canada; Atlantic City and Asbury Park, New Jersey; Hartford, Connecticut; and Augusta, Georgia. Besides Orville and Wilbur Wright, most of the pilots and passengers listed were students who became members of the Wright Exhibition Team. Pilots and passengers include: Griffith Brewer, Walter Brookins, William Starling Burgess, Frank Coffyn, Arch Hoxsey, Ralph Johnstone, Duval LaChapelle, Albert B. Lambert (President St. Louis Aero Club), Phillip O. Parmalee, Norman Prince, Frank H. Russell (first manager of the Wright Co.), Charlie Taylor, and Arthur L. "Al" Welsh [spelled by Coffyn throughout as "Welch"], and Lorin Wright. Most notable is the report of May 25, 1910, which lists the only flight Orville and Wilbur Wright made together, and the first and only flight taken by their father, Bishop Milton Wright. Remarks include notes on modifications and damage to the aircraft, reasons for takeoff failures, and (in some cases) altitude attained in flight. Additional notes on the earlier reports record total flight hours to date for several of the pilots.
