I heard this on the BBC 10 mins ago, that Thomas Kean, the 9/11 Commission's chairman has spoken to a BBC journalist, and taking into account all the evidence at their disposal, this is what he is quoted as saying as being the opinion of the Commission.

I have no links to provide; it's not on the BBC website, yet.

But you never know..., the BBC got it wrong once before, right?

Jim.
