A United Airlines flight from Newark Liberty International Airport made an emergency landing at Washington Dulles International Airport on Tuesday after a passenger allegedly attempted to open an aircraft door during flight.

United Flight 1551, which was bound for Guatemala City, was diverted after the incident involving an unruly passenger. According to reports, the passenger allegedly tried to open one of the plane's doors while the aircraft was at cruising altitude and also assaulted another traveler on board.

Pilots made the decision to divert the flight to Washington Dulles, where the aircraft landed safely. The incident required crew intervention and prompted the emergency landing as a safety precaution.

It is physically impossible to open commercial aircraft doors during flight due to cabin pressurization, which creates thousands of pounds of pressure against the door. However, attempts to tamper with aircraft doors are treated as serious safety violations.

United Airlines has not immediately responded to requests for comment regarding the incident. The Federal Aviation Administration and local authorities typically investigate such incidents involving unruly passengers on commercial flights.
