United States incidents

· On February 27, 2006, at the Will Rogers World Airport in Oklahoma City, in an airliner cargo area (accessible only to authorized personnel), threatening graffiti was found.^[44][45]

· On March 6, 2006 at John F. Kennedy International Airport in New York, an elderly man drove his car onto the runway through two security gates. He made it to an active runway where an Air France aircraft was preparing to land. The man drove around for approximately 23 minutes before being stopped. On the same day a man made it on to the runway by running through a secure gate while it was being opened at Midway International Airport in Chicago. The man made it through one of the three perimeter entrances that did not have a camera, resulting in four different runways being closed down. This incident led to 222 aviation security officers being retrained and a redesign of all perimeter gates.^[45]

· On March 11, 2006, after four years of continuous security breaches and staffing problems news reports indicated that federal officials removed the head of security at Newark Liberty International Airport.^[45]

· On November 1, 2013, a gunman named Paul Anthony Ciancia, age 23, shot and killed TSA agent Gerardo I. Hernandez at the Terminal 3 security checkpoint in Los Angeles International Airport. Ciancia then shot 2 other civilians as he passed security. He made it to the food court in the back of the terminal where federal agents tracked him down and shot him. He was then transported to a trauma hospital where he was treated for his injuries and will be released by the end of November 2 to law enforcement, most likely the FBI. The incident called for a complete shut down in the passenger drop off/departure roadways on the upper level of the airport and caused hundred of flight cancelations across the nation, although international flights had no cancelations. Terminals one, two, and three were shut down and so were the nearby runways, 24L and 24R. Flights that were already in the air and were preparing to land at these runways were either directed to land at the south runways or to divert to Ontario International Airport or Long Beach Airport.
