A JetBlue flight bound for Las Vegas landed unexpectedly Tuesday in Amarillo following a disturbance involving the captain. The FAA says the captain of the flight was exhibiting "erratic behavior" before other crew members locked him out of the cockpit.

The captain was taken for medical treatment once the flight landed in Texas. The co-pilot is being credited with possibly saving the plane from going down by locking the pilot out of the cockpit. He continued to bang on the cockpit door, shouting obscenities and screaming about Al Qaida and a bomb when passengers took matters in their own hands and subdued him.

Here's a great report from CNN with dramatic video taken of the incident.
