Only with Israeli ingenuity can you take a technology that was once reserved only for video games and make it functional in the real world. The news that Israel has launched the anti-hijacking pilot ID system developed by Elbit Systems(NASDAQ:ESLT) is good not just for the company, but for air travel as well.

Starting next year, Israel will require pilots who fly to its airports to use the Security Code System (SCS), a local invention designed to ensure planes that have been commandeered for al Qaeda-style attacks are spotted in time. Israel plans a trial run for the system, using a credit card-sized keypad, next month, in cooperation with five airlines from the United States, Europe and Africa. About 10,000 of the units will ultimately be issued, with Israel bearing the cost. Pilots who fail the authentication test when they approach Israeli airspace will be denied entry. Should a plane go ahead, ignoring further warnings, Israel will consider it hostile and scramble fighter planes for an interception. In the worst case, that could mean an aircraft is shot down.

Several experts familiar with Israeli methodology say the system -- also known as "Code Positive" -- is based on the assumption that a hijacking will take place in one of two ways. Hijackers could either kill the pilots and take control -- as is believed to have been the case in the September 11 attacks on the United States. Or they could force pilots to issue a compliant response to the system in the hope of buying enough time to reach Israel and crash the planes into a target on the ground. In the first case, the hijackers would fail the security check as they entered Israeli airspace, giving military authorities about 15 minutes to launch a response. In the second, Dani Shenar, chief of security for Israel's Transportation Ministry said, pilots would be expected to relay a "May Day" alert.

Let's all hope that this system is never put to use, but in the event of a hijacking, this Israel system could save hundreds of lives.

Stocks for most U.S. and European Airlines fell and then rallied to near their original values earlier today, on arrests of 21 individuals plotting terrorist attacks on trans-Atlantic flights. The sell-off is simple enough to explain, investors being concerned that imposition of heightened security-levels and traveler reluctance to fly would put additional pressure on the ever-ailing industry.

The rebound is explainable as well, as previous terrorist plots have somehow failed to bring the West to its knees. I'm flying the weekend before Labor Day, and wouldn't cancel for the world, though I'll probably (*sigh*) add yet another half-hour to my departure time for SeaTac airport.
