Yours is a rude form of disagreement, is all. Your comments elsewhere:

> This isn't going to happen because a bunch of people in line at an airport isn't a high-value target.

Can you point to research?

> I mean it would suck, of course, but 'bunch of people get blown up at an airport' isn't nearly as worrying as 'large plane falls/is steered out of the sky and into downtown.'

Proof that it isn't as worrying?

> It doesn't have much value to terrorists because it's not as scary and it won't generate vast numbers of photographs.

How do you know it's not as scary? Have you measured?

I don't need to post research. Logically, if a plane falls out of the sky this also presents a threat to anyone on the ground at the time of impact. If people are blown up at an airport, there's no additional risk for those outside the immediate vicinity. This is a consequence of the fact that planes are mobile while airports are not.

Yes, I'm being rude, because by your own admission you are arguing from a position of ignorance and inaccurate prejudice.
