I have an old Readers Digest book here. (bought it at a Goodwill store
many years ago) The book has an article about how the U.S.Navy did a
''rehersal'' a few years before the Japs bombed Pearl Harbor.Way back
then, there were a lot of Japs in Hawaii and other places in the
area.Those Japs were paying very keen attention to exactly how the
U.S.Navy did it.
