O'Brien, John F. (Jack) Jan. 4, 1936 - Feb. 4, 2021 It is with great sadness we share that on Feb. 4, 2021, Jack, 85, passed away peacefully. He was surrounded by his devoted wife, Helene; his adoring children, Lori & Susan; his beloved grandchildren, Kelsey & Ryan; and his wonderful sons-in-law, Richard & Robert. Jack flew the KC-135 Air Refueling tanker as a Captain in the Air Force, and followed that with a 30-year career as a Pilot for American Airlines, mostly as a Captain on the DC-10. After a brief retirement, he spent almost 7 years instructing in the flight simulator for the Boeing Aircraft Company. His was a life well lived, and full of love. Jack will be greatly missed by all and will live forever in our hearts. Rest In Peace My Love. In lieu of flowers, donations to the Alzheimer's Association would be appreciated ... thank you. https://www.alz.org/ For service information, please refer to Jack's memorial page at www.oconnormortuary.com .
