A question for the financial gurus out there re: stock market manipulation?

First off, I know very little about high finance so this might be a real stupid question.

Just before 9/11, over 2 trillion dollars turned up "missing" from the Pentagram. Since I can find no reason for the markets rebounding, is it possible that this missing money is being used to finance this rebound? Or would this be too hard to hide?

They had to have seen this coming eventually, and since they just love to come up with contingency plans for every possible thing that can go wrong, could they have set aside this money for that purpose?
