Current airport security equipment cannot detect certain smaller explosive devices that are capable of causing significant damage. Under a contract with the Federal Aviation Agency (FAA)*, we have developed and successfully tested prototype units of a hardened luggage container which is capable of containing the detonation and suppressing the fires caused by such devices. This container conforms to International Air Transport Association specifications for luggage containers and is designed to provide greater durability than existing containers used in ordinary commercial service. Because this hardened luggage container will cost more to purchase and to operate due to its increased weight over existing luggage containers, we believe that commercial airlines will not readily purchase the containers until FAA regulations require the mandatory use of such a hardened luggage container.
