Less than 1 hour ago (Saturday, September 9 11:09AM ET) I watched a United Airlines DC-10 make a very low pass over BGR (Bangor, ME). I would estimate that the aircraft was at about 9,000ft. It was moving in a south-easterly direction. It did not appear to deviate from it's course either. Does anyone have any information on what could have been going on? I know that BGR is a frequently used divert for transatlantic flights just about to head over the Atlantic, but I was unaware if UAL was using any DC-10's on transatlantic flights. Any information you may have would be greatly appreciated.
