Looking Back / By Mark Albertson: February 1963 – A U.S. Army YUH-1D Iroquois has completed the Air Force phase of its adverse weather testing program and has been turned over to the Army for more climatic torture. In successive periods, the YUH-1D endured climatic testing at Eglin Air Force Base, Florida, Wright-Patterson Air Force Base, Ohio, Eielson Air Force Base, Alaska. The aircraft has drawn favorable reports after testing in temperatures that ranged from 65 degrees below zero to 125 above. The Iroquois “D” model has since been turned over to the Army in Alaska for further testing.
