The hijackers never gained access to the flight deck. The aircraft continued on to Mexico City, where it landed safely and parked at a remote area of the airport. Passengers were allowed to deplane, although the crew were believed to have been held on board at first. Federal police and soldiers reportedly boarded the plane after the passengers had been released and took a number of men into custody.
There is still some confusion as to the exact number and nationality of purported hijackers -- various news media report as few as three and as many as nine. In any case, no explosive device was found on the aircraft, according to Mexico's Transport Minister Juan Molinar.
UPDATE: According to the Bloomberg news service, there was only one hijacker -- a Bolivian man identified by authorities as identified as Jose Marc Flores Pereira -- who said he was inspired by “divine revelation.” Flores reportedly told Mexican authorities that he "took action because today’s date, Sept. 9, 2009, represented an upside-down 666."
Flores threatened the crew from Aeromexico flight 576 with a fake bomb about an hour after takeoff from Cancun, [Public Safety Minister] Garcia Luna said. The pilot informed authorities and later acted as interlocutor between Flores and authorities once the plane landed in Mexico City at about 1:40 p.m. local timeAt least six other passengers had been removed from the plane in handcuffs, but police later concluded that they were not involved in the hijacking plot.
