A United Airlines flight traveling from London Heathrow to Newark Airport diverted to Maine Friday morning due to a Level 3 threat on board.

Flight UA 883 landed at Bangor International Airport at 9:59 a.m. – nearly one hour and 30 minutes before it was supposed to arrive at Newark, according to Flight Aware.
