Does anybody else want to tackle that question? No.
You've noted in your submission, and it has been noted recently, that long queueing lines pose a safety risk as well. I believe you talked about ways of reducing the size of lines through pre-clearances of some sort--“heightened security clearance”. I'm not sure what kind of a clearance you had in mind. I'm also interested in how you would do that for frequent flyers. You chose some interesting classes: officers of the law, frequent flyers, military personnel. We haven't had a Fort Hood experience, but I thought that was an interesting choice.
How do you envision pre-clearance happening? Is it like a NEXUS-style program being applied to domestic air travellers, in which they would pay a fee and they would have to go through a certain amount of questioning, or would it be some other system on that? Anybody can jump in on that, but we'll start with your suggestions.
