| The same aircraft (N7405) that was to later serve as UAL 823, began the day of July 9, 1964 as UAL Flight 609. It appears that a different captain and senior stewardess served on board Flight 609 between Buffalo and Philadelphia, and were not part of the original crew who began Flight 609's operations that day at Raleigh-Durham. In all, two separate crews served on board N7405 while it was classified as United Air Lines Flight 609. | The same aircraft (N7405) that was to later serve as UAL 823, began the day of July 9, 1964 as UAL Flight 609.
