hi Big Duke,
the 5 year anniversaries may have something to do with the fact that every
5 years the surviving members of the crews get to go to the White house to meet
the president. i dont know if it still happens, but i've read both Buzz Aldrins
and Gene Cernans books and others who all mention these 5 year anniversary
visits.
i suppose for Omega these anniversaries are as important as they are to
NASA and the Astronauts themselves.
just a thought.
