9-11 was an intelligence and mindset failure, not a security failure. There's very little "unknown" about the incident, and nothing of any gret significance unknown about how it was accomplished.
Even if security procedures then had been identical to what they are today, absent hardened cockpit doors and with the "humor them" mindset, the hijackings could still have taken place and, in all probability,
would have taken place.
This isn't top secret stuff, Ron. Anyone who understands probability well enough not to draw to an inside straight understands the principles involved here.
