I know that sounds like a really dumb question, but I am researching the U.S. Aviation Industry's immediate response to the 9/11 attacks from a historical perspective (including the closure of the U.S. airspace system, the gradual resumption of flights, the subsequent restrictions on general aviation flights lasting weeks, the creation of the TSA
, the National Guard with their machine guns at the airports, the cultural changes in aviation to a more "security focused" mindset, and how various security measures have been added and removed over the last year and a half).
As part of this research, I am searching Airliners.net as well as the Internet Archive http://www.archive.org
and following news developments as they occured on the FAA's and other websites.
After 9/11, I didn't fly until November 2001, which most of these measures were already in effect. Among these measures was a requirement to show a photo ID
along with your boarding pass at the gate. I realize this measure is currently being phased out, but my question is: Was this requirement implemented immediately after the airports reopened in the days after 9/11, or did several days/weeks go by before this measure was implemented?
