Two US-bound trans-Atlantic flights diverted Fri.

A trans-Atlantic flight from Manchester, England, was diverted to Bangor International Airport on Friday for security reasons, and the plane was being checked by bomb-sniffing dogs, federal and airline officials said. American Airlines Flight 55, en route to Chicago, was diverted for security reasons, an FAA spokeswoman said, declining to elaborate. An American Airlines spokesman in Dallas said the flight, was diverted at the request of the Transportation Security Administration because of an unspecified "security concern." Also on Friday, a US Airways jet flying to North Carolina was diverted to Oklahoma City after an air marshal subdued a passenger involved in an incident with a flight attendant, an airline spokesman said.
