The 1961 President Airlines Douglas DC-6 crash occurred on the night of September 10, 1961, when a President Airlines Douglas DC-6B named Theodore Roosevelt[1] outbound from Shannon, Ireland crashed into the nearby River Shannon shortly after takeoff, killing all 83 people on board.

The aircraft's occupants on the accident flight consisted of 77 passengers and 6 crew members.

[citation needed] The aircraft was on a non-scheduled international passenger flight from Düsseldorf, Germany to Chicago with stopovers in Shannon and Gander, Newfoundland for refueling.

Unable to recover, the aircraft plummeted into the River Shannon 5,000 ft. from the end of the runway.

Poor weather conditions and crew fatigue were also cited as possible contributing factors.
