The Martin 4-0-4 was an American pressurized passenger airliner built by the Glenn L. Martin Company. In addition to airline use initially in the United States, it was used by the United States Coast Guard and United States Navy as the RM-1G.
TWA Flight 260 was the Trans World Airlines (TWA) designation for a flight from Albuquerque, New Mexico to Santa Fe, New Mexico. On February 19, 1955, the 40-passenger Martin 4-0-4 prop plane used by TWA for that route crashed into the Sandia Mountains. Its deviation from the normal flight path, initially believed to be the result of pilot error, was revised to "unknown" given that the contribution of other factors could not be definitively ruled out.
American Airlines Flight 383 was a nonstop flight from New York City to Cincinnati on November 8, 1965. The aircraft was a Boeing 727, with 57 passengers, and 5 crew on board. The aircraft crashed on final approach to the Cincinnati/Northern Kentucky International Airport located in Hebron, Kentucky, United States. Only three passengers and one flight attendant survived the crash.
Pacific Air Lines was a regional airline on the West Coast of the United States that began scheduled passenger flights in the mid-1940s under the name Southwest Airways. The company linked small cities in California with larger cities such as Los Angeles and San Francisco. Flights later operated to Portland, Oregon, and eventually reached Las Vegas and Reno in Nevada.
Scandinavian Airlines System Flight 933 was a scheduled international flight from Denmark to the United States that on January 13, 1969, crashed into Santa Monica Bay at 19:21, approximately 6 nautical miles (11 km) west of Los Angeles International Airport (LAX) in California, United States. The crash into the sea was caused by pilot error during approach to runway 07R; the pilots were so occupied with the nose gear light not turning green that they lost awareness of the situation and failed to keep track of their altitude. The Scandinavian Airlines System (SAS) aircraft had a crew of nine and 36 passengers, of whom 15 died in the accident. The flight originated at Copenhagen Airport, Denmark, and had a stopover at Seattle–Tacoma International Airport, where there was a change of crew. The crash was similar to Eastern Air Lines Flight 401. The crash site was in international waters, but the National Transportation Safety Board carried out an investigation, which was published on July 1, 1970. The report stated the probable cause as improper crew resource management and stated that the aircraft was fully capable of carrying out the approach and landing. The aircraft was conducting an instrument approach, but was following an unauthorized back course approach.
On June 22, 1951, Pan Am Flight 151, flown by the Lockheed L-049 Constellation propliner Clipper Great Republic crashed into a West African hill at an elevation of 1,050 ft (320 m) near the village of Sanoyie in Bong County, Liberia. All 31 passengers and nine crew on board were killed.
Southwest Airlines Flight 1455 was a scheduled passenger flight from McCarran International Airport, Las Vegas, Nevada, to Burbank-Glendale-Pasadena Airport, Burbank, California, that overran the runway during landing on March 5, 2000. The aircraft, a Boeing 737-3T5, registration N668SW, came to rest on a city street adjacent to a gas station. The National Transportation Safety Board found that the incident was due to the pilots attempting to land with excessive speed. They also found that the air traffic controller placed them in a position from which their only option was a go around. Two of the passengers were seriously injured, and there were many minor injuries. As a result of the incident, the airport installed an Engineered Materials Arrestor System (EMAS) at the east end of the incident runway. The aircraft was written off, making the incident the 10th hull loss of a Boeing 737-300. This was the first major accident in the airline's 29-year history.
On Christmas Eve 1996, a Learjet 35A business jet disappeared near Dorchester, New Hampshire, United States. The crash led to the longest missing aircraft search in the state's history, lasting almost three years. Media attention eventually resulted in congressional legislation mandating improved emergency locator transmitters (ELTs) be installed in U.S.-registered business jets.
Boulder City Airport was an airport in Boulder City, Clark County, Nevada, that operated from 1933 through the mid-1980s. It was also known as Bullock Airport during its early history.
Indian Airlines Flight 257 was an Indian Airlines domestic passenger flight operating on the Calcutta–Imphal–Dimapur route. On 16 August 1991, the Boeing 737-2A8 registered VT-EFL crashed into the hilly terrain of Thangjing Hill during its descent, killing all 63 passengers and 6 crew members on board.
The Grand Canyon mid-air collision occurred in the western United States on June 30, 1956, when a United Airlines Douglas DC-7 struck a Trans World Airlines Lockheed L-1049 Super Constellation over Grand Canyon National Park, Arizona. The first one fell into a canyon and the other one slammed into a rock face. All 128 on board both airplanes perished, making it the first commercial airline incident to exceed one hundred fatalities. The airplanes had departed Los Angeles International Airport minutes apart from each other and headed for Chicago and Kansas City, respectively. The collision took place in uncontrolled airspace, where it was the pilots' responsibility to maintain separation. This highlighted the antiquated state of air traffic control, which became the focus of major aviation reforms.
The 1965 Carmel mid-air collision occurred on December 4, 1965, when Eastern Air Lines Flight 853 (N6218C), a Lockheed Super Constellation en route from Boston Logan International Airport to Newark International Airport, collided in mid-air with Trans World Airlines Flight 42 (N748TW), a Boeing 707-131B en route from San Francisco International Airport to John F. Kennedy International Airport, over Carmel, New York, United States.
TWA Flight 529 was a Lockheed Constellation L-049 propliner, registration N86511, operating as a scheduled passenger service from Boston, Massachusetts to San Francisco, California. On September 1, 1961, at 02:05 CDT, the flight crashed shortly after takeoff from Midway Airport in Chicago, killing all 73 passengers and five crew on board; it was at the time the deadliest single plane disaster in U.S. history.

United Air Lines Flight 736 was a scheduled transcontinental passenger service flown daily by United Airlines between Los Angeles and New York City. On April 21, 1958, the airliner assigned to the flight, a Douglas DC-7 with 47 on board, was flying over Clark County, Nevada in clear weather when it was involved in a daytime mid-air collision with a United States Air Force fighter jet crewed by two pilots. Both aircraft fell out of control from 21,000 feet (6,400 m) and crashed into unpopulated desert terrain southwest of Las Vegas, leaving no survivors. The loss of Flight 736, one of a series of 1950s mid-air collisions involving passenger aircraft in American skies, helped usher-in widespread improvements in air traffic control within the United States, and led to a sweeping reorganization of federal government aviation authorities.
Pan Am Flight 923 was a Douglas DC-4 operating from Seattle, Washington to Juneau, Alaska, which crashed into Tamgas Mountain on Annette Island, Alaska, on October 26, 1947. All 18 passengers and crew on board were killed.
TWA Flight 6963, a scheduled Transcontinental & Western Air flight from Paris Orly Airport to New York City with scheduled stops at Shannon Airport and Gander, crashed on 28 December 1946 about 1.5 kilometres (0.81 nmi) west-northwest of Shannon Airport on the island of Inismacnaughton.
British Airways Flight 2276 was a scheduled international passenger service from Las Vegas to London. On 8 September 2015, the Boeing 777-200ER operating the flight suffered an uncontained engine failure and fire in the left (#1) GE90 engine during take-off from Las Vegas-McCarran International Airport, prompting an aborted take-off and the evacuation of all passengers and crew. All 170 people on board survived, but 20 were injured.
TWA Flight 595 was a cargo flight operated from Chicago-Midway Airport in Illinois to Los Angeles International Airport in California. On 24 November 1959 the Lockheed L-1049H Super Constellation operating the flight received a fire warning in its No. 2 engine shortly after departure at Chicago-Midway Airport in cloudy weather and requested to turn back. While turning onto their final approach path they banked excessively exceeding 45 degrees and started rapidly sinking. The aircraft impacted the ground in a residential area at 5:35 am CST about a quarter mile southeast of the airport, killing all 3 crewmembers on board and 8 people on the ground.
