CC Back now with that violent turbulence sending ten people to the hospital after a flight landed in Philadelphia. Now there are concerns it could happen more often and ABC's gio Benitez has the story. Reporter: Overnight new video showing the aftermath of that turbulent American airlines flight this weekend. Ladies and gentlemen, it's your captain. We really apologize for that unexpected bump. Reporter: The ride so rough it sent pillows into the aisle, wine across the floor and drinks flying to the ceiling. Just was totally unexpected.
