Courtesy of the United States Army

Designed by Stanley Hiller, who at age 18 built his first helicopter, the Raven evolved from a 1948 Hiller Model 12. The "G" model, which is a three-seat light utility craft, was used by the U.S. Army, Navy and foreign governments in training and utility roles. Commercial categories were used in crop dusting, forestry, fire fighting, survey and rescue work, as well as, business transportation. In 1960 a Raven set a world's record for landing and take-off at 18,000' on Mt. McKinley, Alaska.

This Army model served with the Massachusetts National Guard.
