ROUGH CUT (NO REPORTER NARRATION).
Amateur video shows commotion on board a JetBlue flight bound for Las Vegas that was diverted to Texas following what federal authorities described as erratic behavior by the captain, who passengers said had to be restrained after he pounded on the locked cockpit door.
The FBI is investigating the incident on Flight 191 from New York, which had 135 passengers on board when the pilot-in-command decided to redirect the plane to Amarillo, Texas.
JetBlue said in a statement the flight was diverted due to a "medical situation" involving the captain but made no mention of any commotion on board.
Passengers who were on the plane described a chaotic mid-flight scene in which a man in a JetBlue uniform, apparently locked out of the cockpit, began banging on the door and demanding to be let inside. Passengers subdued him.
The Federal Aviation Administration cited an "onboard medical emergency" as the reason for the diversion, and said preliminary information showed the co-pilot became concerned that the captain had "exhibited erratic behavior during the flight."
