It returned to Downsview for maintenance between 11-Apr-1955 and 02-Jun-1955 before returning to the unit at Geiger. In Aug 1955 the Air Defence Command underwent a re-organisation and the aircraft was then attached to the 84th Fighter Group. Geiger Field was renamed Spokane in Sept 1960 when our current history of the aircraft ends.

Emily, OR., on 21-Dec-1972 when it suffered category 2 damage (minor/medium) during a takeoff roll whilst attached to the 87th Air Base Squadron, attached to the 4702nd Air Defence Wing at Geiger Field, Spokane Washington. Pilot James W. Atwood.
