Gen. Richard Myers and Major General Larry Arnold(NORAD) when asked about why no jets were scrambled to intercept the planes that hit buildings, both said that there were no planes on ready alert at Andrews AFB or Myers AFB. They said that there are only 2 bases in the entire NE Region with planes on alert(Otis AFB in Massachusetts and Langley AFB in Maryland, due to major budget cutbacks)
This appears to be untrue according to a large body of evidence. Andrews AFB is said to be the main air defense for the capital and Pentagon complex and houses Air Force One. The Military web site on 9/11 said that Andrews serves to defend the capital complex and had 3 squadrons of planes on alert, one being the DC Air National Guard squadron(DCANG).
These planes have been scrambled in the past and can be in the air in about 2 minutes and travel at 30 miles per minute. Also contradicting this are statements by General Myers and Mike Snyder(NORAD) that NORAD was not notified about the plane that hit the Pentagon but that jets from Andrews AFB were scrambled immediately after the Pentagon was hit.
This was confirmed by Richard Clark, National Security Coordinator, and news reports from Washington based news agencies. Later when Donald Arias, Chief of Public Affairs of NORAD, was asked whether jets were kept on ready at Andrews, he refused to answer. Immediately after 9/11, the military web site was changed to deemphasize Andrews AFB and delete references to Andrews capabilities.
