Trans World Airlines Flight 800 (TWA800) was a Boeing 747-100 that exploded and crashed into the Atlantic Ocean near East Moriches, New York on July 17, 1996 at approximately 8:31 p.m. EDT, 12 minutes after takeoff from John F. Kennedy International Airport, on a scheduled international passenger flight to Rome with a stopover in Paris. All 230 people on board died in the crash; it is the third-deadliest aviation accident in U.S. history. Accident investigators from the National Transportation Safety Board (NTSB) traveled to the scene, arriving the following morning amid speculation that a terrorist attack was the cause of the crash.
The de Havilland Canada DHC-6 Twin Otter is a Canadian STOL utility aircraft developed by de Havilland Canada, which produced the aircraft from 1965 to 1988; Viking Air purchased the type certificate, then restarted production in 2008 before re-adopting the DHC name in 2022. The aircraft's fixed tricycle undercarriage, STOL capabilities, twin turboprop engines and high rate of climb have made it a successful commuter airliner, typically seating 18–20 passengers, as well as a cargo and medical evacuation aircraft. In addition, the Twin Otter has been popular with commercial skydiving operations, and is used by the United States Army Parachute Team and the 98th Flying Training Squadron of the United States Air Force.
The de Havilland Canada DHC-3 Otter is a single-engined, high-wing, propeller-driven, short take-off and landing (STOL) aircraft developed by de Havilland Canada. It was conceived to be capable of performing the same roles as the earlier and highly successful Beaver, including as a bush plane, but is overall a larger aircraft.

The aircraft were in an area known as the "Hudson River VFR Corridor", which extends from the surface of the river to altitudes of 800 to 1,500 ft at various locations along the Hudson River in the immediate area of New York City. Within this corridor, aircraft operate under visual flight rules (VFR), under which the responsibility to see and avoid other air traffic rests with the individual pilots rather than with the air traffic controller.

The DHC-3 pilot was able to maintain partial control, but the aircraft sustained substantial damage in the collision and the subsequent forced landing; the pilot suffered minor injuries, nine passengers suffered serious injuries, and one passenger was killed. Both aircraft were conducting sightseeing flights under visual flight rules, which state that the pilot of each aircraft is responsible for visually ensuring adequate separation from other air traffic, commonly known as "see and avoid".
The 2020 Alaska mid-air collision occurred at approximately 8:27 a.m. on July 31, 2020, when a de Havilland DHC-2 Beaver collided with a Piper PA-12 over the Kenai Peninsula, Alaska, approximately two miles northeast of Soldotna Airport, near mile 91.5 of the Sterling Highway.

Transair Flight 810 was a Boeing 737-200 converted freighter aircraft, owned and operated by Rhoades Aviation under the Transair trade name, on a short cargo flight en route from Honolulu International Airport to Kahului Airport on the neighboring Hawaiian island of Maui. Immediately after an early morning takeoff on July 2, 2021, one of its two Pratt & Whitney JT8D turbofan engines faltered, and the first officer, who was flying the aircraft, reduced power to both. The two pilots—who were the only aircraft occupants—began executing the Engine Failure or Shutdown checklist, but became preoccupied with talking to air traffic control (ATC) and performing other flying tasks, and never reached the section of the checklist where the failing engine was to be positively identified and shut down. The captain assumed control but misidentified the failing engine, increased power to that engine, and did not increase power to the other, properly functioning engine. Convinced that neither engine was working properly and unable to maintain altitude with one engine faltering and the other idling, the pilots ditched off the coast of Oahu about 11 minutes into the flight.
On September 4, 2022, a DHC-3 Turbine Otter single-engine floatplane on a passenger flight from Friday Harbor to Renton, Washington, U.S., crashed into the waters of Mutiny Bay near Whidbey Island, killing all ten people on board.
