Arrow Air Flight 1285R, a McDonnell Douglas DC-8, crashes after takeoff in Gander, Newfoundland, killing all 256 people on board, including 236 members of the United States Army's 101st Airborne Division.

Arrow Air Flight 1285R was an international charter flight carrying U.S. Army personnel from Cairo, Egypt, to their home base in Fort Campbell, Kentucky, via Cologne, West Germany, and Gander, Newfoundland. On the morning of Thursday, 12 December 1985, shortly after takeoff from Canada's Gander International Airport en route to Fort Campbell, the McDonnell Douglas DC-8 serving the flight stalled, crashed, and burned about half a mile from the runway, killing all 248 passengers and 8 crew members on board. As of 2025, it is the deadliest aviation accident to occur on Canadian soil. At the time of the crash, it was the deadliest aviation accident involving a DC-8; its death toll was surpassed by the crash of Nigeria Airways Flight 2120 nearly six years later.

The Douglas DC-8 is an early long-range narrow-body jetliner designed and produced by the American Douglas Aircraft Company. Work began in 1952 towards the United States Air Force's (USAF) requirement for a jet-powered aerial refueling tanker. After losing the USAF's tanker competition to the rival Boeing KC-135 Stratotanker in May 1954, Douglas announced in June 1955 its derived jetliner project marketed to civil operators. In October 1955, Pan Am made the first order along with the competing Boeing 707, and many other airlines soon followed. The first DC-8 was rolled out in Long Beach Airport on April 9, 1958, and flew for the first time on May 30. Following Federal Aviation Administration (FAA) certification in August 1959, the DC-8 entered service with Delta Air Lines on September 18.

Gander is a town located in the northeastern part of the island of Newfoundland in the Canadian province of Newfoundland and Labrador, approximately 40 km (25 mi) south of Gander Bay, 100 km (62 mi) south of Twillingate and 90 km (56 mi) east of Grand Falls-Windsor. Located on the northeastern shore of Gander Lake, it is the site of Gander International Airport, once an important refuelling stop for transatlantic aircraft. The airport is still a preferred emergency landing point for aircraft facing on-board medical or security issues.
