Sounds eerily similar to the events of 9/11. A New Jersey factory worker was flying to the Santiago from JFK Airport in New York last evening and boarded his plane. Once on board, the flight attendent asked him to stow his carry-on in the bin above his seat. When the passengers complied with the instructions, the box cutters fell out of his bag.
The flight attendent immediately seized the box cutters and notified the captain of the airplane. All 136 passengers and five crew members were immediately evacuated. Canine units swept the plane for bombs, and re-screened all the passengers. The man who brought the weapons on board simply forgot to take them out of his bag after work. He was not charged with any crimes.
