A serious incident occurred at Denver International Airport involving American Airlines Flight 737, a Boeing 800-1006 flying from Colorado Springs to Dallas. The aircraft was forced to make an emergency landing after the crew detected vibrations in one of the engines, requiring an immediate diversion from the planned route. 

The incident occurred on the evening of March 13, when the plane had been in the air for about an hour. After landing safely in Denver, while taxiing to the terminal, one of the engines suddenly caught fire, causing heavy smoke on the runway. There were 172 passengers and six crew members on board, who were quickly evacuated using emergency inflatable slides. Video footage taken by eyewitnesses captured dramatic scenes of passengers rushing to leave the plane, some of them on the wing of the aircraft, waiting for rescuers, while firefighters actively fought the fire. 

Twelve people suffered minor injuries during the evacuation and were taken to local hospitals for medical treatment, airport spokesman Michael Konopasek said. The Federal Aviation Administration (FAA) confirmed that engine trouble was the cause of the emergency landing, but the exact circumstances of the fire are still under investigation. 

American Airlines issued a statement stressing that the safety of passengers and crew remains a priority. The company is working with the FAA and the National Transportation Safety Board (NTSB) to determine the cause of the incident. Passengers on AA Flight 1006 were provided with alternative flights to Dallas and compensation for the inconvenience. 

The Denver incident is the latest in a series of problems involving the Boeing 737-800, although experts stress that the aircraft type remains one of the most reliable in its class. American Airlines has been using the Boeing 737-800 extensively in recent years on short- and medium-haul routes, including flights from Colorado Springs to Dallas, according to industry sources.
