    Greg and Hanno,

    Great work!  I hope the article will get your achivements to a larger audiance.

    I have been going back over my past cel shots and redoing them with your formulas - by hand - no computer or even calculator.

    Easy and accurate!  One of my hobbies is reading about early navigation and nav instruments.  How wounderful it would have been for some wind tossed sailor to be able to plot his LOP so easyly.  To bad you'all were not around 150 years ago.

    Once again - congrats!

    John H.
