Free fall/symmetrical collapse technically only infers controlled demo.

Clearly it's the only possible conclusion but it is still an inference.

Same with the north side approach evidence. Since it's physically impossible for a plane on the north side to cause the physical damage a flyover is the ONLY possible conclusion.

So while both certainly are direct evidence both conclusions are technically inferred.

(Roosevelt Roberts is equivalent to the nano-thermite paper as being direct evidence or confirmation for what has already been proven to be the only possible conclusion by the evidence in general so we'll leave that out of this analogy)

Obviously any person can view the WTC7 collapse video and calculate the rate of collapse etc but clearly anyone can just as easily view the witness interviews and plainly see that they unanimously point to the north side.

The primary difference is that free-fall collapse proving CD has been mired in scientific debate by experts from both sides and has therefore been effectively neutralized.

Not a single expert would EVER suggest it's possible for a plane on the north side to cause the physical damage at the Pentagon.

Not one has and not one ever will so the debate is reduced to the veracity of the witness claims which logical people who actually view the evidence in full seem to be able to easily understand has been validated to the point of redundancy.
