Says Hardened Deck Doors Are Only A Partial Solution To Cockpit Security
The downing of four commercial airplanes and loss of nearly 3,000 lives on 9/11 was due, in part, to inadequate protection of the aircraft flight deck. Shortly after 9/11, Congress and the FAA required the installation of hardened flight deck doors on most commercial airline aircraft as one of many new layers of security. The hardened flight deck doors are an important improvement to security, but they are not a complete solution to preventing unauthorized individuals from entering the flight deck.
