In light of the terminal attack on Glasglow Airport:

As I detailed in my book AVIATION INSECURITY in 2003 (p. 141), airport sabotage and airport assaults on terminal facilities have historically been preferred methods of attacking aviation by both terrorist and criminal groups.

Some recent events include:

End of 1999 - foiled bombing of international terminal at LAX by Al-Qaeda operatives.

July 18, 2000 - bomb explodes in a garbage can between the domestic and international terminals at Cape Town International Airport in South Africa.

July 22, 2001 - Suicide squads of Tamil Tigers battle with government security forces at Colombo International Airport in Sri Lanka.

July 4, 2002 - terror attack on the El Al counter at the international terminal at LAX.

Aviation has always been and remains the most attractive target for global terror and criminal networks.
