9/11 was like Hiroshima in that new technology was used. Only nobody told us about it. Can you imagine how long it would have taken to figure out what happened at Hiroshima, if the government hadn't told us what took place? I'm guessing many years.
That's another weak analogy, I'm afraid. For a kickoff, the evidence from Hiroshima (one bomber and a single, absolutely enormous explosion) would tell anyone who investigated that some new and exotic weapon was used. 9/11 by contrast is fully explained by hijackers crashing planes (even though you say it isn't - you're just
wrong and you haven't a leg to stand on when it comes to the technicalities of why you believe it's so) so no exotic weapon is required to explain the events of 9/11.
Then there's the fact that the atomic bomb which, although its implementation was developed in great secrecy, was a weapon which had been considered in principle by scientists all over the world for many years. You'll be aware, no doubt, that Nazi Germany was also attempting to develop an atomic bomb. The secret was not that such a bomb
might be built, the secret was how to build a functional bomb. In other words, the
possibility of such a weapon was widely know in scientific circles, unlike your magic Beam of Foam, which even a decade after the event is not even a glimmer on the horizon.
