According to the FAA, the airliner was carrying 231 passengers and 10 crew members and was planning to fly to Honolulu, the capital of Hawaii. The right side engine exploded and caught fire shortly after takeoff.

A video taken by passengers on the plane showed that the metal casing of the engine had been peeled off and flames could be seen.

Witnesses on the ground saw that the aircraft was flying at an abnormally low altitude. Smoke was produced on the aircraft and an explosion sounded. At the same time, debris of the aircraft fell from the air like snowflakes.

According to reports, debris from the explosion of an aircraft engine fell in a community near Denver International Airport. Local police said that some large fragments were found in the suburbs about 40 kilometers north of Denver, and some fragments even fell in front of residential houses. Fortunately, no casualties were caused. Currently, US aviation safety related departments are investigating the accident. The local police reminded the public not to touch or move any debris if they are found, so that relevant departments can investigate.

On the same day, after a Boeing 747-400 freighter took off from Maastricht in the Netherlands, the engine also exploded. Fragments of the aircraft fell from the air, causing minor injuries to the head of an elderly woman on the ground and another A child was burned while picking up debris on the ground. Some damaged engine turbine blades also hit several cars on the ground.

According to reports, the cargo plane was originally planned to fly to New York, but after the accident changed its route and landed in Belgium. The investigation of the accident is currently underway.

Passengers on board: The plane was shaking and heard a huge explosion

On the 20th, after a United Airlines airliner with a malfunctioning engine landed at Denver International Airport, several passengers recounted the frightening moment on board.

Passenger Brenda Dern on board:Everything was fine at first, but suddenly, there was a loud explosion. You could hear the explosion, and then we started to tremble. We were sitting on the wing. I looked out the porthole and saw smoke. I could see something (wreckage) flying towards me, and my daughter was sitting next to the porthole, she was scared. I told her not to look out. We just clenched our hands and prayed for safety. The plane was shaking and shaking during the landing.

Passengers on board:You heard the explosion, obviously, something went wrong. Because the plane is shaking constantly, violently and continuously. At first there was no fire, but there was smoke. After a while, I saw fire. We were sitting next to the porthole facing the wing, so it was difficult not to see it. The people on the plane were in a tense silence. People either hadn’t realized the seriousness of the problem or were in a state of shock.

The malfunctioning aircraft engine exploded and caught fire during an emergency landing, and fragments of the engine casing were scattered in the suburbs of Denver. A photo released by police in Broomfield, Colorado showed fragments of aircraft parts, including the engine fairing, falling on the grass outside a residence. The police said it was fortunate that no one was injured when the debris of the plane fell to the ground.

Rachel Welter, Public Information Officer, Broomfield Police Department, Colorado:Today’s weather is not as cold as last week. There may be hundreds of people coming to this open space, and we have not received any reports of injuries, which is surprising.

Experts analyze the cause of the engine fire is complex but the situation is controllable

On the same day, two engine explosions and fire accidents occurred in the Boeing series of aircraft, which once again aroused people’s attention to aviation safety. So why does the aircraft engine catch fire? Why can the aircraft return safely after the engine stops during flight?

Zhang Wei, director of the Chinese Aeronautical Society:The cause of an airplane engine fire is more complicated. Under normal circumstances, it is due to mechanical failure of the engine, such as broken blades that cause fuel oil, oil leakage or pipeline falling off can also cause fire. After the engine catches fire, a fire detection device will tell the pilot that the engine is on fire. Including this United Airlines 777 not only caught fire, there may also be the case where the fairing opening on the leading edge of the nacelle fell off. This is also more serious, but the condition of the entire aircraft is still controllable. These are the links that will be avoided in the aircraft design process. Therefore, the crew members will implement an emergency landing according to the relevant procedures of how to deal with single-engine or double-engine failure in the prior training. Especially for a large aircraft like the 777, its crew members must have a relatively good flight experience, and must have undergone forced landing procedures on many simulators. The pilot only needs to follow the procedures calmly and calmly. Generally, the plane can be safely flown to the airport for emergency landing.
