That may be interesting, but the fact that airliners could be fooled or even crashed by interfering with the radio signals they rely on is no more a security concern that the fact that airliners can be shoot down with missiles.
- Johnny555 7y agoThere's plenty of reasons why a simple radio attack is potentially more serious than a missile attack. It's a lot easier to buy an SDR than a SAM -- even ignoring the cost differential. I don't know the black market cost of a man portable SAM, but the SDR described in the article is less than $1000 and you can buy it commercially. If you're caught with an SDR in your suitcase, no one will likely know what it is "I use it to listen to shortwave, here, I'll demo", while if you're caught with a SAM, you'll likely end up in jail. No one is going to build a SAM in their hotel room, but it doesn't take much specialized skill to solder together a radio jammer using schematics transferred to you over the internet. And finally, you can use the radio jammer from a backpack and no one will know it's there, but the SAM will leave a trail leading back to you.

Building an SDR which can output a signal strong enough to overpower the ILS array is not going to be cheap, subtle, or particularly easy. ILS is glitchy and pilots are trained to deal with the glitches — a localizer can be disrupted merely by having a plane (or any other large metal object) nearby.
