JetBlue Captain Shut Out of Cockpit by Co-Pilot on Behavior

A JetBlue Airways Corp. captain began acting erratically during a flight from New York today and was locked out of the cockpit by his co-pilot before the plane was diverted to Texas, federal officials said.

The captain had to be subdued by passengers when he tried to re-enter the cockpit after briefly stepping out, the Federal Aviation Administration said in an e-mailed statement. The Las Vegas-bound jet landed in Amarillo, Texas, where the captain was taken to a hospital for evaluation, the FAA said.
