Refuge Manager Richard Guadagno was killed when the commercial airliner he was a passenger on was hijacked while he was returning from vacation.

The plane crashed after passengers, who had heard about the other hijackings, attempted to re-take control of the plane in flight. During the re-taking effort, the plane crashed into a field in rural Pennsylvania. Although it cannot be proven, there is reason to believe that Manager Guadagno was among those who attempted to re-take control of the plane. Manager Guadagno's badge and credentials were found in trees where the cockpit debris had broken off and scattered into, highly suggesting Manager Guadagno was among the passengers who fought back and attempted to retake control of the plane.

Manager Guadagno had been employed with the United States Department of the Interior for 17 years.
