As to Mason's accounts in "Chickenhawk"...a fellow that shared the cockpit with him literally "spits" when he sees the man at the VHPA conventions. It is fore sure a "collection" of other's experiences. He does write a good book until he gets around to singing the "O Poor Me!" chorus at the end.
Mason flew for the 1st Cav in late 65 then was transferred to the 48th Bluestars in '66.
