Trace this offal back to his home village and bomb the living f out of it. This would only be a start, but it is a start. It has been mentioned that he be questioned. Another start. And lastly for the airlines, "You still want us to fly, you morons."
Actually to be more productive and to insure the perps and their kindreds understand the risk they are taking by attacking the USA and it's assets (our airlines and people) I suggest we trace this dog back to his home village and present him to them for punishment. His tribal family should be given the option to put him out of his misery or face massive retaliation from Uncle Sam.
The whole vilage needs to assemble and witness his execution and then their elders should be required to draft a statement absolutely condemning his act of terrorism. Failing that, bomb the f out of them.
