A US domestic flight made an emergency landing after the captain began yelling about a bomb, passengers say.

The airline said a "medical situation" involving the flight captain prompted the landing in Amarillo, Texas, about three-and-a-half hours into the flight.

JetBlue flight 191 from New York to Las Vegas was carrying 135 passengers when a crew member had to be locked out of the cockpit and restrained.

David Gonzales explains how he wrestled its captain to the ground.
