| - | 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.

Stewardess Betty Jones also worked the flight." |
| In the second paragraph, mention is made of "the captain, first officer and one stewardess" arriving in Philadelphia; after having served on board United Airlines Flight 662 taking off from Washington, D.C. I'm assuming the people mentioned include Captain Sabatke, First Officer Young and one of the stewardesses-all of whom would later that same day serve on Flight 823. | In the second paragraph, mention is made of "the captain, first officer and one stewardess" arriving in Philadelphia; after having served on board United Airlines Flight 662 taking off from Washington, D.C.

| Section G, regarding the Battery paralleling switch: This is a two position switch (ON-OFF), spring loaded to the OFF position. When ON, it allows the battery control relay to close to charge the batteries from an external power source. | Section G, regarding the Battery paralleling switch: This is a two position switch (ON-OFF), spring loaded to the OFF position.

| All advisories and airworthiness directives warn of the dangers of extreme heat surrounding the batteries-especially during ground operations. References are made to the "ambient temperature". Inadequate ventilation of battery compartments is given as a possible cause of thermal runaway. | All advisories and airworthiness directives warn of the dangers of extreme heat surrounding the batteries-especially during ground operations.
