Passenger Sees Worker Unscrewing Plane Part Before Takeoff

From Inside Edition.

Before taking off, a plane passenger spotted a mechanic working on the wing. Taylor Hilton says it happened on an American Airlines flight from Dallas to John Wayne Airport in California. Hilton says a flight attendant was also concerned and showed the video to the pilot. She says the pilot came on the intercom and informed everyone that some screws were loose and the dismantled part is for aerodynamic purposes and not required to fly safely.
