I'm reading this Jim Marrs book currently and found some interesting information related to the Department of Defense Directive 3025.1 as this is the
one piece of material that links the Policies, Procedures, and Protocols that would have enacted jets to be scrambled to stop all the flights on
September 11th, 2001 from hitting the World Trade Center Towers 1 & 2, The Pentagon, and the field in Pennsylvannia, which is assumed to have been
directed towards the White House. As well as the Chairman of the Joint Chiefs of Staff document 3610.01A that was the re-write that kept the jets on
the ground because no one gave the order to intercept.
This particular version was submitted January 15, 1993 and does not show the re-write that was done on June of 2001.

The next document is is the Chairman of the Joint Chiefs of Staff, which re-writes that last document. It was submitted on June 1, 2001 just prior to
the September 11th attacks.

This is the document that de-rails all military doctrine in order to scramble the intercept jets, which should also make Secretary of Defense Donald
Rumsfeld responsible to make the intercept orders to happen.
