Crazed Flier Tries to Open Plane Door Two flights diverted over security concerns By Mary Papenfuss, Newser User Posted May 9, 2011 2:00 AM CDT 3 comments Comments A Continental and a Delta flight were diverted yesterday for security concerns. (AP Photo/Paul Sakuma) (Newser) – An apparently deranged passenger tried to open a door mid-flight yesterday on a Continental plane en route from Houston to Chicago. An air marshal tackled the flier when a flight attendant screamed, and the plane was immediately diverted to St. Louis. There were no other details about the passenger, but officials found no indications of a terrorist threat and no explosives were found on the aircraft, according to reports. A second flight enroute from Detroit to San Diego was also diverted yesterday when a note with the word "bomb" was found in a bathroom of the Delta aircraft, reports the New York Daily News. "The captain came on and said, 'You notice we're declining. We're getting ready to divert. It's probably a hoax, but we've got to take this very seriously,'" according to a passenger. No suspicious devices were found, according to an FBI spokesman.
