Hi Ric
----87 octane fuel agreed. You are 2 for 7
----The fuel system modifications during the crash repair, I got from the book Missing by Nesbit, P16 (‘equalising lines added’).
----The weather forecast: according to Elgen Long, P185, ‘...True had sent the message the evening before’.
In the archive
https://tighar.org/Projects/Earhart/Archives/Research/JacobsonDatabase/RADIOMES/MSG7.PDF P79, the message has a date stamp 193706302250
----The position report at 2:18pm (4:18GMT): Chater said ‘...the plane was called and asked to repeat the position, but we still could not get it’. That is due to the poor radio reception, so there is a missing position.
You cannot have it both ways. If the position 150.0E 7.3S is accurate, then it is a dead reckoning position and the time is wrong. If it is not correct, then there is a missing position at 05:19GMT which we have to fill-in. That is why you invented position 157.0E 7.3S and I invented Position 156.
----Sunrise at Howland was 05:45 Howland Local Time. That is specific to the location of Howland and has nothing to do with time zones. It is 06:15 Itasca Local Time when Itasca is in the vicinity and is 07:15 Hawaii Local Time according to whatever convention is in use.
