A Fairchild F-27 crashes into Moose Mountain while on approach to Lebanon Municipal Airport in Lebanon, New Hampshire, killing 32 people.

The Fairchild F-27 and Fairchild Hiller FH-227 are versions of the Fokker F27 Friendship twin-engined, turboprop, passenger aircraft formerly manufactured under license by Fairchild Hiller in the United States. The Fairchild F-27 was similar to the standard Fokker F27, while the FH-227 was an independently developed, stretched version.

Northeast Airlines Flight 946 was a domestic U.S. flight from Boston, Massachusetts, to Montpelier, Vermont, with a scheduled stop in Lebanon, New Hampshire, operated by Northeast Airlines. On October 25, 1968, some time during the evening, the Fairchild Hiller FH-227 aircraft crashed on Moose Mountain while descending on approach. The crash killed 32 of 42 passengers and crew. Of the fatalities, four were employees from the National Life Insurance Company who were returning from a business trip. The fatalities also included a reporter for the Barre Daily Times and six social workers of the Vermont Head Start Supplementary Training Program on a conference trip. Ten passengers survived the crash with minor or moderate injuries. After the crash, Northeast Airlines continued flight service until its merger with Delta Air Lines in the early 1970s.

Moose Mountain is an 8-mile (13 km)-long ridge located in the eastern part of the town of Hanover in Grafton County, New Hampshire. The mountain is flanked to the north by Holts Ledge, at 2,110 feet (640 m), and to the south by Shaker Mountain, at 1,690 feet (520 m). It is traversed by the Appalachian Trail, a 2,170-mile (3,490 km) National Scenic Trail from Georgia to Maine. Moose Mountain is outside the White Mountain National Forest, but the trail runs through a narrow corridor along the ridge which is administered by the U.S. Forest Service. The trail can be accessed from the south along Three Mile Road in Hanover, and from the north along Goose Pond Road in Lyme, New Hampshire.
