1.TWA Lockheed Super and United Airlines Douglas DC-7 Incident:

On June 30, 1956, TWA Lockheed Super and United Airlines Douglas DC-7 collided with the Grand Canyon to collide with each other. TWA Lockheed Super had 64 passengers with 6 crew members and Douglas DC-7 had 53 passengers with 5 crew members.

Dead: 128

Reason: Both aircraft were controlled by Instrument Flight Rules (IFR). The pilots of both of them changed the route already fixed, because the airways were not directly controlled from the control room. According to the rules of the time many points were fixed. These were fixed routes of different companies.

Change: Air traffic control system has been improved by spending 250 million dollars at that time due to this accident.

Result: After the improvement in the air traffic control system, there was no crash in the US for 47 years. After this incident, the Federal Aviation Agency (now administration) was started in 1958. It is the responsibility of Air Safety.

 

 

2-United Airlines Flight 173 Incident:

On December 28, 1978 United Airlines Flight 173 crashed in Portland, the sub-urban area of ​​Oregon. This aircraft was about to land at Portland International Airport.

Dead: Deaths of 19 including 8 crew members.

Wounded: 21 passengers.

Reason: Captain’s failure to monitor the aircraft’s fuel. With this, the oil was exhausted from both the engines. Due to the supply of the fuel stopping, the landing gear got disturbed and the attempt of the emergency landing was unsuccessful. “10 Plane Crashes That Changed Aviation “

Change :
– All crew members were given cockpit training.
– New cockpit resource management (CRM) was adopted.
This technical training was made mandatory for other members of the aircraft.

Result: Crew members succeeded in saving crash landing of DC-10 in Sioux City of Iowa in 1989, due to improvements.

 

 

3-Air Canada Flight 797 (McDonnell Douglas DC-9-32) Incident:

On June 2, 1983, a McDonnell Douglas DC-9-32 from Air Canada Flight 797 was going to Montreal from Texas.

Immediate emergency door and other gates were also opened, but people could get out of the plane, even before the explosion in the cabin from the fire. There were 46 people in the plane.

Dead: 23

Reason: Fire in the back part of the plane. The crew member ignored the fire, but why it could not be detected.

Change :
– Smoke detectors and automatic fire extinguishing machines were found in toilets of all planes.
– A fire resistant layer was installed on the seats of Jetliners.
– Lightening arrangements were also made in the floor of the plane. This will reduce the hassle of frequent smoke travelers.

result :

After 1988, more and more safe and fire-resistant interior was being prepared in planes.

 

4 – Delta Airline Flight 191 (Lockheed L-1011-385-1):

The afternoon weather in Dallas, Texas, on August 2, 1985 was a bad one. The temperature was high but there was also moisture. At 4:03 p.m., Delta Airline’s Flight 191 was flying from the runway. There were 167 passenger riders in this Lockheed L-1011-385-1. At some height of 800 feet, something strange happened. An explosion occurred and in a few seconds the plane came down on the runway and highway. A vehicle came in its grip.

Number of dead: 137

Causes of the accident: Conditions of creating celestial electricity in the atmosphere will be created. This was the situation due to a weak frontal system.

Reform: After the crash, NASA prepared wind-windshield detector radars.

Result: This incident has recorded only one such accident since the incident.

 

5- Aeromexico Flight 498 Incident:

After the aerial accident in Grand Canyon in 1956, the ATC system made different routes of the airlines. It helped in preventing the accident. Despite this, on 31 August 1986, a private 4-seater Piper Archer aircraft could not detect the control room system in Los Angeles. AeroMaxico DC-9 pilot made a big mistake and the passenger plane going to the lading collided with LAX. Both pieces of the plane were scattered in the radius of 20 km of the resident area.

Dead: 82

Reason: The control room system could not detect the small plane in the airport area.

Change :
– Transponders were used to allow small aircraft to enter the controlled area. This electronic device gives full details of the status of the plane and the height of its flight.
– Aircraft companies were required to set up TCS-2 anti-combat system.
– In such situations, the transponder pilot gives the correct instructions to save the plane.

Result: In the US, no small plane after this system has collided with an airliner.

 

6- Aloha Airlines, Flight 243, (Boeing 737-200, N73711) Incident:
