An Illinois man has been sentenced to 10 months in prison for trying to open a jet door mid-flight.

The sentence for 34-year-old Reynel Alcaide of Burbank, Ill., was handed down Tuesday in U.S. District Court in St. Louis. He pleaded guilty in December to interference with flight crew members and attendants.

Alcaide also was sentenced to three years of supervised release and ordered to pay restitution of more than $7,000.

Alcaide was on a Continental Airlines flight traveling from Houston to Chicago on May 8 when he repeatedly tried to open an exit door. Passengers and crew members subdued him, and the flight was diverted to Lambert Airport in St. Louis.

A prosecutor says Alcaide reported marital problems and said he had tried to commit suicide previously.
