I think you missed the satire in their post

Anyway, the chance of a real Terroristtm being on any flight is hardly even measurable - the chance of a Terroristtm being on a flight where the door accidently popped open is laughably small. I wouldn't burn a single brain cell fretting over it.

All this worrying about 'disclosing secret information' is equally laughable - does anyone here think that a determined enemy is going to stopped by our procedures? Sorry, but no - if someone wants to do something, and puts even a few hours of planning into it, their mission is, unfortunately, likely to be successful in spite of everything being done by both governments and industry members to prevent it.

I wonder if the TSA even knows how many domestic (and Int'l/Caribbean) commerical service flights in the US operate without a flight deck door at all.
