    Gary:
    
    Thanks for jogging my memory by posting something Earhart related - I'd
    meant to reply to this earlier, but it fell through the cracks...

    I'll defer to your expertise on this one, since you have more experience
    with overwater flights than I do - but my big question would be why they
    planned to arrive at Howland in the early-morning hours when glare would
    definitely be a problem while trying to locate a tiny speck of land in the
    vast ocean.
    
    Just seems to be another in a long series of mistakes, oversights,
    miscommunications, etc. that led up to the accident. As Capt. Laurance F.
    Safford (who was also responsible for the Mid-Pacific Strategic Direction
    Finding Net, and the decoding of the Japanese PURPLE cipher) put it in his
    analysis of the Earhart flight during the 1970s: "Poor planning, worse
    execution."

    Long's book is the best one out there. He used the same methodology that I
    did. I have some differences with him. He places the uncertainty of airborne
    celestial LOPs at +/- 15 NM and I use +/- 7 NM which is in keeping with all
    the text books and also with the Federal Aviation Regulation requirement.
    His assumption ends with a larger area of uncertainty than mine. I also
    disagree with his explanation of why they didn't land at Dakar, see my posts
    last month about this.

    Another disagreement with him is that he marks out 90 degrees  of of the
    circle as having reduced visibility due to the glare of the sun. I measured
    the glare on the sea at sunset with my sextant and it is only 5 degrees
    wide.
    
    As you can see, these are minor disagreements and don't change the
    conclusions much.
    
    
    Regarding the experimental high frequency DF equipment on Howland, there are
    no documents showing that Earhart knew of its existence, it appears that it
    was a last minute addition by Mr. Black when sailing out on the Itasca. You
    would think that if she did know about a plan to have it installed on
    Howland that in one of her radiograms to Itasca she would have asked to have
    its installation confirmed before relying on it yet there is no mention of
    it in her messages.

    LOL! What a surprise (not...). Though it probably still won't stop Ric and
    his band of merry "explorers" from enticing even more people to help
    bankroll their wild-goose chase expeditions. Has anyone ever really thought
    about the fact that her radio transmissions were really strong (signal level
    5, according to the Itasca radio log) up until the time she disappeared, and
    if they'd managed to land anywhere that was above water the radio would
    still be operable (granted with no fuel they couldn't run the plane's
    generator(s), but the ship's batteries should have lasted at least long
    enough for them to get out a distress call - or several).
    
    I went back and looked at some of my Earhart source material, and it turns
    out that the Itasca had set up a DF station on Howland that would work on
    frequencies that she was using, but apparently the batteries went dead
    before they were in range and could use the DF steer.
    
    Have you ever read _Ameila Earhart - The Mystery Solved_ (Elgen and Marie
    Long)? The authors make a very compelling case for their theory (also backed
    by a ton of research, interviews, etc.) - no bizarre conspiracy theories,
    just an honest reporting of the facts and the obvious conclusions (which
    also happens to agree with my own theory about what happened to them, and
    that the plane is at the bottom of the ocean somewhere NW of Howland).
