A United Airlines flight was forced to divert following a mid-air emergency in which a passenger allegedly attempted to open a door. The incident occurred on Flight 1551, which was traveling from Newark Liberty International Airport to Guatemala City with 145 passengers and six crew members aboard.
Incident Details
The pilot decided to divert the Boeing 737-8 MAX due to an unruly passenger. Air traffic control recordings suggested that the passenger tried to open a plane door while the aircraft was in flight. The individual then reportedly attacked another person who intervened. Crew members and passengers restrained the person until the plane landed safely at Washington Dulles International Airport in Virginia on Thursday afternoon, where police met the flight.
Airline Response
A United Airlines spokesperson confirmed that the flight was cancelled after the incident, and passengers were provided overnight accommodations. A replacement flight was added for Friday morning. The airline stated: "United flight 1551 landed safely at Washington Dulles and was met by law enforcement to address an unruly passenger. The flight was cancelled, with a replacement flight added for Friday morning, and customers were provided overnight accommodations."
The Federal Aviation Administration (FAA) reported that the crew notified authorities of a passenger disturbance, and the flight landed around 8:30 p.m. local time on Thursday, May 21.
Physical Impossibility of Opening Door
It is physically impossible for a passenger to open a commercial airplane door at cruising altitude due to mechanical locks and atmospheric pressure. Modern airliners use "plug-type" doors that are larger than the opening frame, similar to a drain plug. To open, the door must be pulled inward first, which is prevented by the pressure differential. At 35,000 feet, the cabin is pressurized to a lower altitude, creating about 8 to 9 pounds of pressure per square inch against the door, making it impossible to open in flight.
