Having met Mr. Randi in person (as has CF Larsen), he is aware of what goes on at the Forums in a general way, but only posts on major topics or to give his view on how the board should be operating. The man does not have the time to spend hours here like we do.
That said, I am sure he is aware of the Conspiracy sub-forum and the 9-11 discussions here. As mentioned above, Mr. Randi is not an engineer or a demolitions expert, but I imagine he knows a few to ask questions of.
Considering that his right-hand lady (Linda) just had an emergency appendectomy and he is about 10 months recovered from heart surgery, I would not expect a quick reply to TS missive. Which he will undoubltedly use
as "evidence".
One last thing; Mr. Randi can be among the funniest and most charming people you can ever meet; but he does not suffer fools gladly. If TS gets his answer, he probably will not enjoy it.
