Could training at a towered airport have prevented the ADIZ bust

The CNN pilot-reporter, Miles O'Brien, made a good point. These guys took
off from an uncontrolled airfield, implying that they were not adept with
ordinary ATC as would pilots be who were trained or who are resident at a
Class D or C towered field. I remember how difficult it was to train at a
Class D airport, wishing that I could have made my early training hours
easier at an un-towered field. Now I'm grateful for all the angst and
mike-fright I went through and eventually overcame.
