2041 AD is roughly when the truth about 9/11 will be generally available. It will be much the same as the revelations about the JFK murder conspiracy. In other words, it's about, always about, WHO BENEFITTED. LBJ murdered JFK to beat a murder charge and a lot more, and to get the presidency. His co-conspirators in the CIA and Big Oil had their own interlocked reasons. Their enablers like mulatto homosexual J Edgar Hoover benefitted as well.
The simplest easiest way to "solve" 9/11 is to look at who benefitted.
And don't kid yourself. Obama benefitted. A lot. He's no JFK. He's much more of a LBJ.
