Yes, I do.
Well, I traditionally make it only a yearly thing to careen Truthers around and that is in September when it's worth remembering.
Usually when someone writes...
My questions do not mean that ..., I just want to cover all grounds. ... that person is at the point of tightening up a few loose ends.
Asking on the faith of the planes and passengers you are obviously not tying up a few loose ends but rather asking fundamental, basic questions. Your questions are very good ones. Keep thinking critically and don't take crap from anyone.
From the very little you wrote, I would read that your caught between what common sense tells you and your desire, or particular disposition to distrust the authorities.
Of all that's written above, none of it strikes me as new and it's all re-heated, long discredited stuff. I do find it ironic that a post written using the "military" brand as a symbol of authority be used where the same military are so oft lambasted. Go figure !!
Anyhow, if you have a very specific paragraph you'd like investigated please do tell which, I have grown a serious list of resource for such questions.
