         JUSTIFICATION :

               The individual aircraft histories presented in this SEA Unit Review were gained from the USAF Individual Aircraft History
               Records which can be found in the Air Force History Research Agency (AFHRA) at Maxwell AFB, AL.

               In most cases mutations from one unit to the other were administrated correctly, but sometimes there are gabs and sometimes
               other sources (documents found in the AFHRA files) gave different reassignment dates.

               The research into these individual aircraft records and the arrangement into tables and reviews was done by Johan Ragay.

                I like to thank Mr. Robert L. LaPointe (website : PJ's in Vietnam) for using some of the unit activation/deactivation data,
                published on his webpages under the tab " Outline".
