( CNN ) -- The JetBlue pilot arrested after an apparent midair meltdown last week was ordered held without bond during a brief appearance before a federal judge in Amarillo , Texas , on Monday morning , the U.S. Attorney 's Office said . The U.S. magistrate ordered that Clayton Osbon , 49 , be held in the Randall County jail until a detention hearing to determine his bond on Thursday , the prosecutor 's spokesman said . Osbon , the captain of JetBlue Flight 191 , has been in custody at a hospital where he has been treated since last Tuesday , when he was arrested and later charged with interfering with a flight crew . His remarks and erratic behavior on the planned five-hour flight from New York 's Kennedy International Airport to Las Vegas led the co-pilot to lock Osbon out of the cockpit , according to a federal criminal complaint . Crew and passengers subdued Osbon as he screamed and banged on the cockpit door so hard that the first officer thought Osbon would come through , the document said . The complaint says Osbon began making remarks during the flight that concerned the first officer , who was his co-pilot . `` Osbon yelled over the radio to air traffic control and instructed them to be quiet . Osbon turned off the radios in the aircraft , dimmed his monitors and sternly admonished the FO ( first officer ) for trying to talk on the radio , '' the U.S. Attorney 's Office in the Northern District of Texas said in a written statement . `` When Osbon said 'we need to take a leap of faith , ' the FO stated that he became very worried . Osbon told the FO that 'we 're not going to Vegas , ' and began giving what the FO described as a sermon . '' The flight data and cockpit voice recorders from the jet , which made an emergency landing in Amarillo last week , will be analyzed , officials have said . CNN 's Todd Sperry contributed to this report .
