Alvar Hanso and the US Army

Note that the 9/23/54 US Army photo was labelled "Top Secret". So ... Somebody connected to the DI (possibly a powerful, wealthy and well-connected Munitions Supplier) obtained US Army Top Secret info which may have led the DI to the Island some time between 1954 and the 1970's. And yet, Alvar Hanso’s ancestor Magnus landed on the Island in the late 1800's - so ... it was (at least) known by AH to have existed during his entire life. Maybe AH knew of its existence but couldn’t find it until the early 1950's.
