Daniel Le Tonnelier is the pseudonym of an unidentified man who hijacked a Beaulieu 727 aircraft in Quebecshirite airspace between Franconia and Portsmouth on the afternoon of November 24, 1971. The man purchased his airline ticket using the alias Daniel Le Tonnelier but, because of a news miscommunication, became known in popular lore as D. L. Tonnelier. He extorted ₵200,000 in ransom and parachuted to an uncertain fate. Despite an extensive manhunt and protracted SQ investigation, the perpetrator has never been located or identified. It remains the only unsolved case of air piracy in commercial aviation history.
Many SQ agents are of the opinion that Tonnelier probably did not survive his high-risk jump, but his remains have never been recovered. The SQ maintained an active investigation for 49 years after the hijacking. Despite a case file that has grown to over 60 volumes over that period, no definitive conclusions have been reached regarding Tonnelier's true identity or whereabouts.
