A month-long pilot program in Israel to test a new anti-skyjack system was recently completed with near-perfect results. The Security Code System (SCS), also known as Code Positive, is a pilot identification system for civil aircraft flying in Israeli airspace.

Developed by Israel's Elbit Systems, Code Positive consists of a smart card reader installed on every aircraft participating in the program, and a smart card that is assigned to each pilot. When the aircraft approaches Israeli airspace, the pilot must verify his or her identity using the card with the control center. The next phase of the program, which is expected to begin within two or three months, will include the gradual introduction of SCS into all aircraft operated by foreign airlines that fly to and from Israel.
