Two men aboard a Delta flight from Maine to Atlanta are being hailed as heroes after helping to subdue a passenger making disturbing threats. James Tunnell, an ex-corrections officer, was aboard Delta Flight 1249 from Portland to Atlanta on Thursday, when he and his companion Ashley Decker heard another passenger causing a commotion from the rear of the aircraft. When the man locked himself in a restroom, Tunnell ran to the back of the plane, where he was joined by another man who identified himself as a member of the Coast Guard. A flight attendant provided the men with handcuffs, and the two then worked with crew to wrangle the man back into his seat.
