>then the next best thing to do would be to simply destroy the airport
I've said this before, the way to cause most disruption is a suicide bomber in the body scanner.
However both this and any attack in the airport will not create the same sort of terror reaction that the thought of being blown out of the sky would. So in terms of terror it would not matter whether flights are in reality terror proof, sowing the seeds of doubt is sufficient. Leave an external HDD full of glue and bolts to be found in a suitable place and that's what you've got. Terror for virtually nothing.
