US Customs officials have detained two passengers from an Air France flight bound for Dulles International Airport near Washington. Transportation Security Administration officials say the plane was diverted to Bangor, Maine because they discovered that one of the passengers is on the US no-fly list. The plane eventually flew on to Dulles - arriving more than two hours late. TSA spokeswoman Yolanda Clark says the other person detained was traveling with the banned passenger. Both are in the custody of local law enforcement in Bangor. She says TSA is investigating why the passenger was allowed to board the plane in Paris. Passengers, who didn't know there was a problem until they crossed into US air space, say everything went smoothly. Some were alarmed when they heard about the incident.
