This article reviews aircraft security procedures already in place for U.S. airlines, assesses their limitations, and describes some technologies under development that may improve aircraft security, particularly against terrorists' use of plastic explosives concealed in luggage.
Abstract
Trained operators using X-ray machines and metal detectors can detect most weaponry in airline luggage and on passengers. Specialized security procedures are used by all U.S. carriers for international flights from high-risk countries. Modeled after the system used by the Israeli airline El Al, the procedures, commonly referred to as a risk analysis system, provide full security for all aspects of each flight. There are special procedures for loading cargo, conducting aircraft searches, monitoring catering services, guarding the aircraft, x-raying all baggage, and interviewing each passenger. Since these security procedures are costly and time-consuming, extensive research is underway to develop technology that will screen carry-on and checked baggage quickly, thoroughly, and accurately. Ideally, the device would instantly screen a passenger and the passenger's baggage and be 100 percent effective in the detection of weapons and explosives. Such a device is not yet available; however, several promising devices are under development and, in some cases, undergoing field testing. Many of the new devices are designed to detect explosive compounds by detecting the nitrogen in the explosives. The technology of these devices is described in this article.
