A plane made an emergency landing at Boston's Logan Airport Thursday after a passenger became unruly and attempted to open a cabin door in flight, ABC News affiliate WCVB reported. Michael Ensalaco, 40, of Mooresville, N.C has been charged  with interfering with a flight crew.

The passenger had to be restrained by other fliers, according to Massport, the agency that runs Logan Airport.

The plane landed safely. There were 50 passengers on board.

The plane, Air Wisconsin 3801 was flying from Portland, Maine, to Philadelphia. Air Wisconsin is a regional airline that flies for US Airways.

The crew became concerned with a passenger's behavior and ordered the landing in Boston.  It was originally thought that he may have been suffering from a medical issue.

The passengers were not in danger of the cabin door opening during the flight. After a rash of unruly passenger behavior in 2011, an American Airlines spokesperson told USA Today, "It's not possible to open an aircraft door in-flight."
