A United spokesman says a cabin pressure issue forced the Amsterdam-bound Flight 986 that had left San Francisco on Sunday afternoon to divert to Bangor International Airport early Monday.
Passengers said oxygen masks dropped and the jetliner quickly descended. Passenger Ben Friedman told WABI-TV it was scary, but most people remained calm.
An airline spokesman says the 13 crew members helped 197 passengers safely exit. The airline provided accommodations with plans to fly to Newark, New Jersey, later on Monday, and then on to Amsterdam.
Bangor's location makes it a good place for trans-Atlantic flights to divert for refueling, mechanical problems or unruly passengers. It's the nation's last major airport for outgoing flights and the first for incoming flights.
