Our speaker was introduced by program chair Harvey Clark.  Pamela Davis has a long and distinguished career working in the field of airline security, primarily with U.S. Air which has now merged with American Airlines. She is a Washington, DC. native.  Pamela holds a multi-engine commercial pilot's license.   
The U.S. is still the top target for terrorists.  Every U.S. airline has a corporate security department that acts as the police department for the airline. They have broad responsibilities that range over many security issues such as terrorist threats, theft, fraud, cyber attacks, hijackings, passenger security, and airport security.  The airline security people are part of a complex, multi-agency security system that includes many Federal agencies including TSA.
 
Pamela took us through an interesting chronological history of threats to airlines, many of which preceded the 9/11/2001 attacks.  She started the series with the bombing of a plane in 1955 by a man who wanted to collect on an insurance policy on the life of a person in the plane.  New types of threats led to the development of new counter-measures to thwart them.  She mentioned air marshalls (think hijacking), then metal detectors (think carry on guns, knives, bombs), then X-raying of luggage (think Lockerbie luggage bombs), the formation of TSA and airport security check points (think 9/11), the removal of shoes (think Richard Reed, the shoe bomber), the banning of carry-on liquids and gels over a certain size (think foiled bomb preparation in flight) and whole body scanners (think the underwear bomber).  Lately many of the threats are coming in the way of cyber attacks to gain information, gain control of systems or totally disrupt systems.
 
Pam's presentation stimulated a spirited period of many questions from club members that took us past the usual closing time.
