The AP reports that the first anti-missile defense system has been installed for testing on a commercial jet, a FedEx cargo carrier. The system is intended to detect the launch of a shoulder-fired missile at takeoff or landing, and disable the missile with a laser beam. Sen. Barbara Baxter (D-California) is one of the supporters of the system. She and other members of Congress are hoping to equip all US commercial passenger liners with this system in 20 years, at a cost of billions of dollars. Is this good common sense or the costly future of a society hobbled by fear of terrorism?

No passenger plane has ever been downed by a shoulder-fired missile outside of a combat zone. But terrorists linked with al Qaeda are believed to have fired two SA-7 missiles that narrowly missed an Israeli passenger jet after it took off from Mombasa, Kenya, in November 2002.

1) First you have to get ahold of a missile. Hollywood notwithstanding, shoulder-launched SAMs are relatively rare, even in mainstream standing armies. The scales of issue just aren't all that large. They are expensive and fragile units, much more so than any other weapon, so they don't get handed out to just anyone.
Probably the largest concentration was in North Vietnam during the 60's, but North Vietnam had tons of time to accumulate them, and a direct threat (daily US bombing raids) to counter.
There just aren't a lot of them out there to be had.
2) Then, if you can find one, it has to be operational. Explosives and electronics have shelf-lives, and as mentioned, these things are fragile. If it hasn't been well treated, there's a nontrivial chance that some critical component will fail to function, and it won't fire, guide, or explode.
3) If you've got one and it is operational, then you have to find a trained operator. Even "fire and forget" missiles require some skill to operate, and even if the weapon is American-proof simple to use, the operator still needs to be familiar with the ideal operating envelope - what aspect should the target be engaged with (head-on? tailchaser? deflection?) Does the position of the sun matter? Do you aim at an engine, or centre of mass? Lead or lag?
4) Assuming an operational missile and a trained operator who takes a good shot, the accuracy rate of these devices is not high. I'd imagine a commercial jet would be an easier target (although with cooler running turbofan engines, maybe not) but even so, there is a high statistical percentage of these missiles that will fail to impact even when fired in perfect conditions - they work best in volleys.
5) Assuming a hit, the odds on downing the aircraft are not good. Airliners are big, solid aircraft, and shoulder-fired missiles by design cannot have very large warheads - you have to package propulsion, guidance, and warhead into something light enough to be carried by a single person. Being struck by a missile is certainly unpleasant, but I'd expect any modern airliner to be able to suffer catastrophic failure of a single engine and still be able to fly (long enough to get back down at least). That's not to say that the missile *couldn't* bring down a liner (sever the controls to a control surface and I think you've got a crash) but neither are you looking at a Hollywood style giant fireball.
While it is certainly *possible* that one could experience a terrorist organization bringing together a fresh missile, a trained operator, and a lucky shot, it's not very *likely* - to the point where I think the defensive device is just silly.

They detect the flame out the back of the missle. Chemicals given off by the rocket motor burn across the spectrum (visible, UV and Infra-red). The optical sensors on the aircraft pick up the burning, specifically in the UV range. Sunlight in this spectrum does not get through the upper atmosphere, so it is essentially "dark". Only a few other things emit at this range are things like arc-welders, but software can be used to eliminate these to improve the false alarm rate.

Terrorists will just attack somewhere else. The most obvious target is mass transit. Leave a bunch of bombs on the New York Subway, just like they did with the trains in Madrid- that would probably be a lot easier than smuggling a Stinger missile into the US. Or plant an IED on the Northwest Corridor and wait for a packed Acela train to go over it. Plant a limpet mine on the bottom of a ferry- if you can sink it fast enough you could kill a few hundred people.
It's all just a show: most of the security efforts I've seen in place do comparatively little to make anyone safer, they're just designed to make us *feel* safer. They're not security, they're a security blanket.

Re:Brilliant! (Score:5, Informative)
The system will be mounted on the belly of the aircraft, so an air-to-air missile launched from above will not be affected by it. It's possible to perform aerobatics in a passenger aircraft (rolls and such) but even so it is highly unlikely that a system designed to detect the launch of a ground-to-air missile could do anything about air-to-air missiles. If they could, then every aircraft in the military arsenal of sufficient size to carry the system would have one already, for missile point defense in flight.
In addition, passenger craft are subsonic (with a notable exception or two) while any contemporary jet is supersonic, and passenger craft are ungainly pigs compared to fighter aircraft. Thus you don't even need missiles; cannons would do the job just fine. You could literally line up and blow off the engines without substantial effort.

I could see a system like this for a plane that has to fly over Iraq or South Africa, but inside of the US/Canada/Europe/Australia/Asia it doesn't seem to be necessary, worse, a system like this is probably going to require massive power and have considerable complexity. Highly complex pieces of equipment are liable to malfunction at some point and possibly even cause a crash.
No, installing something like this in every airplane in the US fleet is just not realistic. Having it as an option for people who have to fly near areas where terrorists have shoulder fired missiles and a grudge against the west is good though.
Re:Need? (Score:5, Informative)
Shoulder fired anti aircraft missiles are built primarily to shoot combat jets out of the sky. The amount of explosives (less than a pound of something like HT3) is negligible. The missile's primary objective is to rip the skin open of the wings/fuselage, having the explosive go off inside the jet is a bonus. The sheer air friction of a torn fuselage will rip a small jet apart.
Apply this to a commercial airliner. Most missiles will hit the fuselage, and lets assume a gaping hole was created. The most that will happen will be rapid decompression (at altitude), significant flight handling differences, and maybe some people will get sucked out of the plane. More than likely a commercial airliner would land after being hit with a shoulder fired SAM. The only chance of taking out a significant chunk of the plane would be to hit it just after takeoff and get the fuel tanks, but you can't exactly pick where you want the missile to hit the plane.
They should invest the research funds towards making better baggage scanners.

The more society spends on 'security' the harder it is to undo that security. Build a Great Wall of China and it keeps the invaders out. Build a Great Wall of the Rio Grande and it keeps the Mexican immigrants out. But given time or motivation, invaders and immegrants find ways around the walls.
The more society relies on 'security' the more devestating it is when that security fails. These planes will have protection against missles (how many times have planes been shot down by missles anyhow?!). I am sure some motivated criminal will determine that using a high powered large caliber rifle or remote controlled airplane with C4 attached works just as well for bringing down a plane; or something else we haven't even considered.
In my view, the only way to minimize acts of terror, keep illegal immigrants at home, and make the world 'safe' is with economic development. If a person has a full stomach and something to do with their hands so they can avoid hunger tomorrow, then that person is too happy and busy to 'terrorize' or risk life and limb crossing the dessert.
Money spent on walls, airline bomb closets and anti-air to air missle lazers, and even super cool rail guns are all poor investments, in my view. Better to spend the money on starting businesses, funding schools, and giving incentives to entrapeneurs. If everyone is fed and busy, the world is as safe as it could be (though still not perfectly safe).

There are not going to be actual "gangs" of Islamic fundamentalists running around in your neighborhood, killing people in front of your kids. First, there are not actually enough fundamentalists to make this happen. Second, we do have a police force, you know -- it's their job to deal with gangs. You could argue that they don't do a particularly good job of that in some parts of LA, but to be honest, even there is nothing like it is in the movies. People with families live in Compton. There are gangs, to be sure, but even there, people killing others in front of your kids is an uncommon occurence, not an everyday affair.
Let's talk about a "reasoned" response: 3000 people died on 9/11, that's all. It's tragic, but come on. How many people die in car crashes every year? The reason people keep bringing it up is because, every year, nearly 40 thousand people do!
Here's the reality of the situation: 6 years later, we've accomplished nothing that is actually relevant to 9/11. Osama Bin Laden is still at large, as much as the government tries to understate his importance. No replacement for the WTC is on the horizon, despite much in the way of planning.
However, we have used the event to justify tremendous, unreasonable spending on cockamamy schemes like this one that will do exactly nothing to help prevent terrorism. Seriously, the people that came up with the 9/11 plan and executed it were brilliant, from a logistical, strategic, and creativity perspective. Do you really think they're a one-trick pony? That now that they've done 9/11, the only possible terrorist attack they can think of involves running a plane into a building? Because that seems to be the way our administration thinks.
We've gone to the ends of the earth to make flying a pain, hurting our economy and annoying our passengers. And for what? To prevent another 9/11? Why not just blow up a building? Why bother with the plane? We're expecting it, it would be stupid.
Maybe George Bush was right, after all -- maybe they did attack us because they "hate our freedom." Lamentably, our response seems to be to throw our freedom away to appease them.
