True enough - and while not wanting to disagree with your analysis, I'm not sure 
it's a valid comparison. 

Your flights had the benefit of a very recent and very close known position (i.e. 
Oxnard or Santa Paula airports, depending on where you departed from) that 
Earhart and Noonan didn't after 20-some hours over the open ocean. 

I would certainly hope that any halfway-decent navigator would be able to find 
an island (or at least an LOP through it) that's only a few tens of miles 
offshore with that as a starting point...  ;-)
