1916 Curtiss JN-4D "Jenny" Military Tractor

1916 Jenny The "Jennys" were the workhorses of the U.S. Air Mail Service, although the machines flown here at College Park were the JN-4H model, as opposed to the earlier JN-4D on display in the museum.

This aircraft was built in 1916, but its history before its discovery in pieces near San Antonio, Texas remains unclear. The U.S. Army gathered up the remaining bits and the Virginia Aviation and Machine Company, Ltd restored the biplane in the 1990s. A monumental task, this meticulous restoration took over 12,000 man-hours to complete and retained up to 60% of original Jenny parts. Some of the parts are original Curtiss Jenny parts, but not original to this particular aircraft. Parts that had to be fabricated were made in strict accord with original Curtiss factory drawings.
