US FAA
The FAA has been implementing red teams since the Pan Am Flight 103 over Lockerbie, Scotland. Red teams conduct tests at about 100 US airports annually. Tests were on hiatus after September 11, 2001 and resumed in 2003.
The FAA use of red teaming revealed severe weaknesses in security at Logan International Airport in Boston, where two of the four hijacked 9/11 flights originated. Some former FAA investigators who participated on these teams feel that the FAA deliberately ignored the results of the tests and that this resulted in part in the 9/11 terrorist attack on the US.
