The question of head winds Both the last forecast sent to Earhart and Noonan and their reported conditions agree It is most likely that they were encountering headwinds as high as  knots It is also certain from her reports that they had climbed considerably above the optimum altitudes early in the flight and thus had to have had considerable additional fuel consumption I would  refer you to Kelly Johnsons instructions prepared for Earhart on the flight profile necessary to achieve optimum range Given the variables which we cannot know I would imagine that she had  hours reserve by the time she reached the vicinity of Howland  but that might be optimistic I cannot know how much fuel she had One radio log indicates she stated  hour but did that include the remainder of  octane One thing for certain is that she did state she was low on fuel and that cannot be reasonably interpreted as meaning she was fat This is OPINION but given the anxiety she seemed to have in her voice and her use of the term low on fuel coupled with the forecast and reported by her winds it is probable that they were far less than the optimum  hours given still air and best altitude operations would have made possible  Mr Gillespie can dismiss her report of ground speed and winds aloft as well as the far higher than optimum altitude she reported less than half way into the flight with the term speculation in a foot note No one did at the time nor can I OPINION but Though this is my Opinion I CAN document several aspects of it including  the airplane designers instructions and how his instructions for an optimum profile differed from her report Her reports and how they coincided with the last forecast the USN sent her from Hawaii And thus how if Kelly Johnson was right True had not incompetently read the information about winds aloft from reporting stations near her path and she was not lying then she MUST have had significantly higher fuel consumption than the optimum profile would have produced How much that is a question I cannot specifically answer But for all three to be totally wrong for there have been still air for True to have been incompetent in his interpretation of winds aloft reports and Earhart to have been lying about the winds she reported and her speed takes a bit of speculation I cannot indulge in Mistakes were made but I cant imagine everyone made exactly the right combination of mistakes and deceptions to allow the Electra to have achieved its optimum performance on the flight Given the time which they apparently from reports and signal strength spent searching  for Howland Island it is unlikely that they had a big reserve when the last signal was heard OPINION
