    Re: Fw: Chichester's Calculations ( Sine-Cosine method)

    Thanks, Gary and Yay for Capt. Phil! His time-sight method is what I
    carried for backup after I got my Tamaya NC-2 and before I had my
    cut-down of 229. Weems was quite a pioneer in developing simplified
    methods of sight reduction. I wonder why he isn't mentioned much these
    days. -Hewitt
