This still has to be determined. Sooner or later we will get confirmation from the ATCC as to whether or not this "report" was real.
Another question: were there any Americans on board this "tourist" plane?
I am being very cautious before jumping to any conclusions. AT this point, I would not rule anything out.
I will add this: it is very suspicious that this happened the very day that the OBL tapes were to be released.
CNN still has the one d*mn photo that doesn't even show the impact of the crash.
