Delta Air Lines Flight 723

Delta Air Lines Flight 723 was a Douglas DC-9 twin-engine jetliner, operating as a scheduled domestic passenger flight from Burlington, Vermont to Logan International Airport in Boston, Massachusetts, with an intermediate stop in Manchester, New Hampshire. On July 31, 1973 at 11:08 AM, while on an instrument landing system instrument approach into Logan in low clouds and fog, the aircraft descended below the glidepath, struck a seawall and crashed, killing all 89 occupants; two people initially survived, but later died of their injuries.
The DC-9-31, registration N975NE, serial number 47075, was manufactured in September 1967 and had 14,639 flight hours at the time of the accident. The jetliner was one of the aircraft that Delta Air Lines acquired in their 1972 merger with Northeast Airlines, to whom the aircraft was originally delivered. The flight crew consisted of Captain John Streil and First Officer Sidney Burrill . Captain Streil, a highly experienced pilot, had accumulated roughly 14,800 flight hours throughout his flying career. He had 17 years of experience as pilot-in-command and had been flying DC-9s since 1970, with 1,457 hours logged in them. First Officer Burrill was also an experienced airman, with just under 7,000 flight hours, including more than 200 hours on the DC-9. Occupying the cockpit jumpseat was a third pilot, Joseph Burrell , who was in training and was not yet qualified on the DC-9.
