NORAD Involved in Extensive Exercises

I have contacted NORAD public affairs several times in the latter part of October, 2004 to inquire about possible locations of descending space junk.  My inquiries are related to investigations of UFO sightings in the U.S. and Canada.  When first making my inquiry I have always talked to someone in public affairs (no voice-mail).  However, the public affairs officer has only called back once. The response that I have been receiving is that the dispatcher would check with the "Early Warning Center" regarding my request. However, no response was received. In one instance I later called regarding my request and was told that NORAD personnel were involved in a training class.  In another inquiry a military contact told me that NORAD was extensively involved in special exercises and did not have time to answer my question.

Comments:  Obviously something is going on at NORAD.  Normally NORAD is responsive to my requests.  I suspect that preoccupation with exercises is related to the election and other possible threats.  I have learned in a previous request that these exercises frequently involve scrambles of aircraft and the intent is to simulate a real threat.
