Security
At least six (formerly two) undercover agents accompany each international El Al flight, sitting amongst passengers whilst holstering firearms. All El Al pilots are former Israeli Air Force fighter pilots, and all El Al flight crew members are trained in hand to hand combat. In fact, most El Al employees have served in the Israeli army (since national service is compulsory in Israel).
El Al security procedures also require that all passengers be interviewed individually prior to boarding, allowing El Al staff to identify possible security threats. All passengers are classified on a basic 3 tier threat scale: Israelis and Jews are usually classified as the lowest threat, Westerners are usually classified as medium level threats, and Arabs (particularly males) are usually classified as high threat. In addition, all luggage must pass through a decompression chamber. El Al is the only airline in the world that passes all luggage through this special chamber.
The El Al fleet is also the only commercial airline fleet in the world to be equipped with anti-missile countermeasures.
As a result of the tight security, only one El Al plane has been successfully hijacked, in 1968 (see below for details).
