Federal prosecutors are asking that a JetBlue captain who left the cockpit of a Las Vegas-bound flight screaming about religion and terrorists be held without bond.

Pilot Clayton Osbon smiled Monday at his wife and JetBlue employees who came to his first court appearance. The 49-year-old is charged with interfering with a flight crew for his bizarre unraveling last Tuesday.

Osbon was not asked to enter a plea during the hearing. A judge is expected to rule on the bond issue during a detention hearing Thursday.

Passengers wrestled Osbon to the ground after witnesses said he ran through the cabin screaming about Jesus and al-Qaida. They tied him up with seat belt extenders until the plane made an emergency landing in Amarillo, Texas.
