Curtiss JN4-D Jenny:
The Post Office Department took over the operation of the Air Mail Service after a three-month trial run by the Army on August 12, 1918, and set up operations here at the College Park Airfield. The Department purchased six Standard aircraft expressly for the service, but also utilized the six Curtiss JN4-Ds that the Army had converted for their short airmail stint. These Army trainers were equipped with Hispano Sulza 150 hp engines instead of the Curtiss OX-5, 90 hp engines traditionally used by the "Jenny", such as the one shown here. |
