On July 31, 1973, Delta Flight 723 left Burlington, Vermont on a scheduled domestic passenger flight to Logan International Airport in Boston. The plane, a Douglas twin-engine DC-9 jetliner, had an intermediate stop in Manchester, New Hampshire, where it picked up passengers stranded there when their flight to New York was canceled due to thick fog. After leaving Manchester, it began its flight to Logan. Although it was behind its scheduled arrival time, the pilots were planning to land at Logan. It began its descent into Logan at 11:08 a.m., using an instrument landing system (ILS) approach. As it descended through low clouds and fog, it went below the glide path and crashed when it struck a seawall. At the time of the crash, the weather was partial obscuration and fog. It had a ceiling of 400 feet and half-mile visibility. Winds were light.

Captain John Streil was the flight captain; the highly experienced captain was assisted by First Officer Sidney Burrill, who was also an experienced airman. There was also a third pilot in the cockpit, Joseph Burrell, who was in training at the time.
