A Delta Air Lines McDonnell Douglas DC-9-30, similar
to the one involved.

On July 31, 1973, Delta Flight 723 struck a concrete seawall
as it descended into Boston’s Logan International Airport
amid heavy ground fog.

The collision broke off some of the fuselage and the plane
slimed into the ground, breaking apart and bursting into
flames.

Almost all on board died instantly in what became the worst
air disaster at Logan and in all of New England.
