I noticed a huge difference in amount of gallons per document.
Unfortunately there remains a great deal of mythology, confusion and controversy about many elements of the Lae/Howland flight for which documented facts are readily available. Marty has provided several links.
Plus, am curious to know back in that time frame how often a pilot renewed their pilots license and why Amelia never renewed her license before her fateful flight.
Earhart did renew her license. The entire episode is described in detail in Finding Amelia starting on page 16.
