A disturbed man was detained at JFK Airport after he sneaked into the cockpit of a JetBlue plane early Tuesday, sources said.

An airline employee discovered Jarrett Stroud, of Atlantic City, NJ, sitting by the window in the cockpit shortly after the jet arrived from the Dominican Republic at 1:43 a.m., according to Port
Authority Police sources.

The jet was inspected and Stroud was taken to Jamaica Hospital for psychiatric evaluation.
