Timothy W. Duffy of Churchville, PA died peacefully surrounded by his family on Thursday, November 2, 2017 at Abington Jefferson Health Hospice at Warminster.  He was 71.

Timothy was the beloved husband of 48 years to Laureen M. (Butella).

Born in McKeesport, PA, he was the son of the late James A. and Dorothy A. (Englert) Duffy.

Timothy graduated from the United States Naval Academy in 1968 and the Naval Postgraduate School in Monterey, CA with degrees in aeronautical engineering.  He was a Naval aviator and career Naval officer.  He loved flying, earning his “Wings of Gold” in Pensacola, FL followed by duty assignments with VP-4 in Barbers Point, Hawaii and Patrol Wing 1 Cubi Point, Philippines flying the P-3 Orion.  Upon returning to the United States he transitioned to the Aerospace Engineering Duty Officer community and worked at the former Naval Air Development Center in Warminster, PA, the former Naval Air Propulsion Center in Trenton, NJ and finally the Naval Air Engineering Center in Lakehurst, NJ before retiring as a Commander.

Following his Naval service, he began his second career in defense contracting and worked with, among other things, the world’s largest human centrifuge used to train astronauts and later, fighter pilots to manage the strenuous demands of high g forces on the body.
