In planning the flight, Navigator Fred Noonan would have determined the Point of No Return.
 

Over the decades, plenty of speculation has accumulated about where Amelia Earhart's flight actually ended.  The most credible locations, based on her final radio transmissions, are within a couple hundred miles of Howland, including this one. Others call for radical off-course routes or, as in this one, a course-reversal toward Lae.  The Point of No Return puzzle is based on speculations about Fred Noonan's flight planning not on potential locations of crash-sites.
