    I would much appreciate a copy, Gary.
    
    I am not starting a new thread because the subject is related to your
    commentary on the difficulties of making celestial observations. Could you
    give me a reference to anything on the attempts by Byrd and Weems to use the
    single-body fix  method by taking sun shots through the open hatch of their
    seaplane?
