Pilot of Jetblue Flight 191 after the plane took off of NY: "We are NOT going to Vegas".

A federal criminal complaint against Clayton Osbon, the 49-year-old JetBlue captain who had a mid-air meltdown on Tuesday, suggests he was acting strangely as Flight 191 was taking off from New York for Las Vegas.

The complaint, NBC News has learned, states Osbon arrived late to JFK and missed the crew briefing. As the flight took off, Osbon mentioned “being evaluated by someone” to the first officer, spoke of church and needing to “focus.” He asked the first officer to take the controls as he made incoherent comments about religion and then said, “things just don’t matter.”

Over the radio, Osbon yelled at air traffic controllers to be quiet and admonished the first officer for talking on the radio and then said, “we need to take a leap of faith.” He spoke of sins in Las Vegas and said, “we’re not going to Vegas,” according to the complaint.
