The 15-year-old boy who stowed away on a flight from California to Hawaii in the wheel well of a 767 didn't just breach security by climbing into the plane, he also jumped the fence at San Jose International Airport and stayed on the ground for more than six hours without getting caught.
#1) IS THE BARBED-WIRE FENCING HIGH ENOUGH?
Fencing is usually the first layer of defense in airport runway security, according to Kay.
At San Jose airport, there is six miles of fencing that reaches six feet tall, but "if someone really wants to get over that fence, it’s not inconceivable that they could have."
#2) SHOULD SOMEONE IN THE AIR TRAFFIC CONTROL TOWER HAVE SEEN HIM?
Kay considers air traffic control towers the second layer of airport defense.
With the amount of personnel in the towers who can see the entire airfield, he said "anyone trying to walk across the airfield should be an easy target."
#3) IS THERE ENOUGH MONITORING OF SECURITY CAMERAS?
There are 200 cameras at San Jose airport, but officials do not have video of the stowaway getting over the fence – just video of a person they believe is the boy walking on the tarmac.
Kay believes the airport should put a higher priority on closed circuit camera monitoring, but adds, "there will always be some sort of blind spot. You’re never really going to eliminate everything."
#4) IS EVERYONE ON THE GROUND PAYING ENOUGH ATTENTION?
Just as the eyes in the sky should be vigilant, people on the ground such as caterers, baggage handlers and pilots, who already check the plane before takeoff, also need to be alert for security breaches.
While they may already be aware, "maybe the procedures and protocols need to be a little bit better," Kay said.
