The Sikorsky CH-53E Super Stallion is a heavy-lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. The less common MH-53E Sea Dragon fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and performs heavy-lift duties for the Navy. The Sikorsky CH-53K King Stallion, which has new engines, new composite rotor blades, and a wider aircraft cabin, is set to replace the CH-53E and is beginning to enter service in the 2020s, but most of the Super Stallions are still in service as are the MH-53E Sea Dragons.
New York Airways was an American helicopter airline in the New York City area, founded in 1949 as a mail and cargo carrier. On 9 July 1953 it may have been the first scheduled helicopter airline to carry passengers in the United States, with headquarters at LaGuardia Airport. Although primarily a helicopter airline operator with scheduled passenger operations, New York Airways also flew fixed wing aircraft, such as the de Havilland Canada DHC-6 Twin Otter 19-passenger STOL twin turboprop aircraft.
The Sikorsky S-92 is an American twin-engine medium-lift helicopter built by Sikorsky Aircraft for the civil and military helicopter markets. The S-92 was developed from the Sikorsky S-70 helicopter and has similar parts such as flight control and rotor systems.
The Sikorsky H-34 "Choctaw" is an American piston-engined military helicopter originally designed by Sikorsky as an anti-submarine warfare (ASW) aircraft for the United States Navy. It has seen extended use when adapted to turbine power by the British licensee as the Westland Wessex and Sikorsky as the later S-58T.
British International Helicopter Services (BIH), owned by Bristow Group, is a British-owned helicopter operator.

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.
Los Angeles Airways Flight 417 was a Sikorsky S-61 helicopter that crashed on August 14, 1968 in the city of Compton, California. All eighteen passengers and three crew members were killed. The aircraft was destroyed by impact and fire. According to the National Transportation Safety Board the probable cause of the accident was fatigue failure. The accident happened when the yellow blade, one of five main rotor blades, separated from the spindle that attached the blade to the rotor head. Following failure, the helicopter was uncontrollable and it fell to the ground. The fatigue crack originated in an area of substandard hardness and inadequate shot peening.
On 6 November 1986, a Boeing-Vertol Model 234LR Chinook helicopter returning workers from the Brent oilfield crashed on approach to land at Sumburgh Airport in the Shetland Islands. At 2.5 mi (4.0 km) from the runway the helicopter had a catastrophic forward transmission failure which caused the tandem rotor blades to collide. The helicopter crashed into the sea and sank. Forty-three passengers and two crew members were killed in the crash; one passenger and one crew member survived with injuries.
Los Angeles Airways (LAA) was a helicopter airline founded in October 1947 and based in Westchester, California, which offered service to area airports throughout Southern California.
Los Angeles Airways Flight 841 was a Sikorsky S-61 helicopter that crashed at 5:50 p.m. on Wednesday May 22, 1968 in the city of Paramount, California. All twenty passengers and three crew members were killed. The aircraft was destroyed by impact and fire. The probable cause of the accident was a mechanical failure in the blade rotor system, which then allowed one blade to strike the side of the fuselage. The other four blades were then thrown out of balance and all five rotor blades broke and then the rear fuselage and tail separated from the rest of the airframe. The cause of the mechanical failure is undetermined. At the time, it was the worst helicopter-related accident in U.S. aviation history, not to be surpassed until the 1986 Grand Canyon mid-air collision which killed 25.
British Airways Helicopters was a British helicopter airline from 1964 to 1986.
G-BJVX, a Norwich-based commercial Sikorsky S-76A helicopter operated by Bristow Helicopters, crashed in the evening of 16 July 2002 in the southern North Sea while it was making a ten-minute flight between the gas production platform Clipper and the drilling rig Global Santa Fe Monarch, after which it was to return to Norwich Airport.

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.
The East Pakistan Helicopter Service refers to the scheduled helicopter services operated by Pakistan International Airlines (PIA) in East Pakistan during the 1960s. It was one of the earliest air services of its kind in the world and one of the most extensive helicopter networks in history.
On 27 October 2018, a Leonardo AW169 helicopter crashed shortly after take-off from Leicester City's King Power Stadium in Leicester, England, while on route to Luton Airport. All people on board—the pilot and four passengers, including club owner Vichai Srivaddhanaprabha—were killed in the crash. The Air Accidents Investigation Branch attributed the crash to a loss of yaw control owing to a failure of the tail rotor control linkage.
Chicago Helicopter Airways was a short-hop commuter service that ran between O'Hare International Airport, Chicago Midway International Airport, Meigs Field, Winnetka, Illinois, and Gary, Indiana from 12 November 1956 to 1974. Incorporated on 13 November 1926 as Helicopter Air Service, mail services were provided to 54 post offices, three times per day. It started carrying passengers in 1956, when a government program offered grants to promote helicopter commuting. In 1960 126 flights carried 6,000 passengers every day, primarily using Sikorsky H-34 helicopters the civilian version, the Sikorsky S-58C. With the disaster of Chicago Helicopter Airways Flight 698, business quickly dropped off so that by 1963 it was down to 3,000 passengers per day. Grant money ran out in 1966. CHA made an unsuccessful try at a limited-service comeback in 1969 and the company closed down in 1974.
