CHARLOTTE, N.C. (AP) - Students from the United Arab Emirates were taken off a Thanksgiving Day flight from Charlotte to Washington and rescreened by security, causing the flight to be delayed for more than four hours.
    
Three of the students told WJLA-TV in Washington (http://wj.la/vWN9fl ) they were pulled from the plane and questioned about the purpose of their trip and whether they had military training. They now want an apology.
    
A US Airways spokeswoman confirmed the flight was delayed because of a security issue, but referred further questions to the Transportation Security Administration. A TSA spokesman referred questions back to the airline.
    
A spokeswoman for the Charlotte airport said the flight crew reported suspicious activity to airport police who then responded. She referred further questions back to US Airways, which again declined to comment.
