"Booen told Flight that the wavelengths involved are the same used by commercial cell phones, which - apparently - means there is no risk to airliner avionics."

So by that logic, I could point my phone at a missile and it'll be deactivated!

If it's powerful enough to disable the guidance system in a missile that's most likely shielded (at least slightly) against this sort of thing, then what chance has a commercial airliner, that isn't designed to withstand these sorts of attacks going to have...
