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

Nota Bene: 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.
