The Department of Homeland Security is reviewing additional precautions for domestic and international flights. Frequent flyers are already familiar with routine air travel procedures: "There are emergency exits over the wings. In case of sudden loss of cabin pressure, oxygen masks will drop from the ceiling. In the event of a water landing, your seat cushion may be used as a flotation device," and so on. Proposed for this spring is a new anti-terrorism measure: "In the event of a hijacking or other terrorist attack, your tray table may be detached and used as a shield or a bludgeoning device. After reattaching, please return your tray tables to a full upright and locked position."
The Transportation Safety Agency has considered this as an alternative to a proposal in which, rather than removing all potential weapons from travelers, instead each adult traveler would be provided with a fully charged taser so that the sneakiest or most dangerous person is not the only armed traveler aboard a flight.
The measures are under consideration as part of Airline Procedural Review #1 (APR-1).
