A Comair flight crew required a man dressed in traditional Muslim attire who spent what the crew believed was an excessive amount of time in the restroom before takeoff to exit a plane at the Memphis airport. Authorities searched the plane and found nothing suspicious. "It's been classified as a security scare. I'm not so sure I would classify it that way," airport vice president Scott Brockman said. "The pilot and crew, it's their responsibility to err on the side of safety."
