RedIbis - I'm not one for getting involved in 9/11 CT issues, partially because I'm a little late to the party, so to speak, and it would take me an enormous amount of research to get up to speed, which I don't really consider a good use of my time. But I have to admit that I have somewhat of a fascination in reading the ongoing 9/11 CT arguments, to see how convincing they seem, even if only on face value, and how well, or poorly, they're presented.
I like to think I can be, and am, objective when presented with arguments. The problem with your postings here, though (and I haven't read any other 9/11 CT threads to which you might have contributed, so I can't know whether this is typical), is that you haven't presented any real argument, certainly not well-supported arguments. All you've really done is pose questions, most if which you could, I suspect, and therefore should, if you're motivation is genuine, obtain answers to through sensible, proper enquiry. The remaining questions, as others have pointed out, are invalid, in the sense that you shouldn't, as a member of the general public, realistically expect readily available answers to them.
You seem to expect that the respective Authorities are under some sort of obligation to investigate Flight 93 to the nth degree, and make all of its findings publicly available, simply to pre-empt any and every possible question that could conceivably be asked, regardless of source or motive. The World doesn't work like that. It would be great if it did, but then you'd need to find a new hobby, which might not be a bad thing, for all concerned.
RedIbis, please don't take offence, but you really should, as should others like you, take a step back, a deep breath and then a serious reality check on life generally, and your motivations in particular. I remember the first time I became involved in geocaching (I trust you know what that is) as a 40-year-old adult(!). It was good fun, derived a great sense of excitement and satisfaction, and made me feel like part of a special community that has found its purpose in life. Then the novelty wore off and I reverted to more grown-up pursuits. I kinda look back sometimes and wonder what it was that I found so appealing. I suppose it was the sense of adventure - rising to the challenge and trying to find the answer to the puzzle, or better still, being crowned the "first to find"!.
I can't help feeling that your motivations, and those of similar ilk, are not disimilar, the only difference being that you don't really want to find the cache, because that then signals the end of the search, and it's the search that appeals to you, not the truth. It's like the bitter-sweet feeling of completing a jigsaw that you've been painstakingly working on for weeks, feverishly slotting the last few pieces into place because the end is in sight, but then pausing with the final piece poised, not really wanting to place it into position because of the sudden realization that the "challenge" will then evaporate instantaneously, never to present itself again.
So, how do you manage your motivations and expectations? Simple, you mentally dispose of some pieces of the "jigsaw". That way you can ostensibly attempt to complete the picture, but you know it'll never happen. Whatever you do, no matter how hard you try, or whatever help is offered by others, the puzzle will never be properly solved. Trouble is, if you're honest with yourself, you know exactly what the picture is from the start. You don't need to complete the jigsaw to know. It's on the box for all to see.
