"Do the orders still stand?" -- Military aide to Vice President Navy Capt. Douglas Cochrane
Was there a stand down on 9-11? In a sense yes, but there is no evidence that a stand down order was issued. There would be no reason for VP Cheney to issue a stand down order, since he issuing a shoot down order, would have the same effect. I will proceed to show this as a fact along with the disturbing fact that the President of the United States, and the Secretary of Defense, both deserted their posts in a time of war. These two individuals who are the only ones authorized to issue shoot down orders of civilian aircraft, created the stand down, by deserting their posts, and then further disgraced themselves, and their offices, by lying to the American people.
"On September the 11th, enemies of freedom committed an act of war against our country." - Pres G Bush
First - the players involved:
Condoleezza Rice -- National Security Adviser
Dick Cheney -- Vice President of the United States
Donald Rumsfeld - Secretary of Defense
George W Bush - President of the United States
The National Military Command Center (NMCC) is the most secure part of the Pentagon and, at the time of the 9/11 attacks, was "the focal point within [the] Department of Defense for providing assistance" to law enforcement efforts in response to aircraft hijackings in U.S. airspace, according to military instructions.  In response to the attacks on New York and Washington, the job of the NMCC, according to the 9/11 Commission, was "to gather the relevant parties and establish the chain of command between the National Command Authority--the president and the secretary of defense--and those who need to carry out their orders." 
This comes from DNotice.org, in a piece entitled 'The NORAD Papers III,' which follows two other informative reports from them about NORAD that people have submitted to 911bloggger.
Their article begins:
In The NORAD Papers and The NORAD Papers II we learned from government/military documents, media reports, university curricula, etc. dating from before 1995 to 1999 that NORAD since its founding in 1958 was tasked with three missions:
1. surveillance and control of the airspace covering the United States and Canada;
2. providing the NCAs [National Command Authorities] with tactical warning and attack assessment of an aerospace attack against North America; and
3. providing an appropriate response to any form of an air attack.1
The Officiial Excuse for 9/11, 'Failure To Imagine' Excuse Debunked!
The Bush Administration offered up the 'failure to imagine' excuse for the response to 9/11.
President Bush: "We knew he [Osama bin Laden] had designs on us, we knew he hated us. But there was nobody in our government, and I don't think [in] the prior government, that could envision flying airplanes into buildings on such a massive scale," he said.
Well according to NORAD's own statements, Project Positive Force, a Special Operations unit tasked with thinking like a terrorist and how they might attack the United States, "imagined" that a hijacked plane would be crashed into the Pentagon.
Terry Ropes, the Special Operations officier, defended the idea, but Pacific Command thought it was too unrealistic. Numerous warnings in the late 1990's also included a possible plot to fly an explosive laden aircraft into an American city.
The information contained in the explosive report, also discusses NORAD's regular intercept exercises of hijack aircraft prior to 9/11!

Activists and researchers have long tried to understand how the highly sophisticated U.S. military could have failed so completely to stop the attacks that took place on September 11, 2001. Statements made by several U.S. military personnel who were deeply involved in the crisis response that morning suggest an alarming method that may have been used to sabotage normal defenses. Revealed here for the first time, this is one possible reason that the military was in such a state of paralysis until it was too late to make a difference.
