Very strong pattern to the letters...and that takes planning.
The planes came on a Tuesday. The letters all have Tuesday dates on them.
Which could mean the connection was opportunism of a big national event to send out the letters.
The handwriting proves that they were not written by an American. Were any of these scientists of ME or European, or Eastern European, extraction? The handwriting was from someone who learned to write on a different continent.
Maybe the “T” for Tuesday was a tip off about what was going to happen.
Al Queda typically doesn’t go out of its way to minimize killing people as the Amerithrax mailer did (it seems the mailer perhaps did not realize the danger of power leaking from the envelopes) which is why I’ve always been very dubious of a connection.
The dates are different:
“09/18/01 and 10/09/01”
but there was a missing hijacker. And possibly other cells grounded that day.
The 9-11 attacks were already a conspiracy of agents of terror. One more agent to mail the letters is not a stretch.
This would have taken advance knowlege of the WTC and Pentagon attacks to have been sent out on the same day. It would have taken at least months of planning to coordinate this closely. There would almost have had to have been some connection. I just wish Americans would wake up to the fact that 94% of the population of the world and therefore 94% of the evil in the world is from outside the US, when they harp on America being only 6% of the world population to promulgate their convoluted explanations of everything.
And weren't some of the letters sent to areas in Florida that had connections to Atta and fellow scumbags? That would support your theory.
