Why hasn't the Amelia Earhart mystery been solved with irrefutable proof like a wrecked airplane or are you convinced it has been solved?

The Pacific is a big freaking place, 99% of it is covered with water, and in the 1930's they didn't have satellite tracking systems. All navigation was done either by way points or dead reckoning, you plotted a course and lit a shuck for the horizon. You make a 0.1 degree error in your course heading or get into any kind of cross wind and it would screw you up royally. You might also remember that not to long ago a modern jet airliner went down in the Gulf of Siam and we still to this day don't know what happened to it.

Difficult to impossible to find a small airplane under near 4 miles of Pacific Ocean. Took them 70 years to find the Titanic (in the Atlantic), and that was massively bigger than her airplane. And they knew the general area where the Titanic sank. Her flight & where exactly it went down isn't known (only estimated). US Flight 19 went down only a few hundred miles off the US coast, and they haven't been found either.

Maybe she had mechanical problems. And maybe she just miscalculated her next re-fueling stop?? She wasn't that great a navigator.

A small plane at the bottom of a vast ocean is not easy to find, nobody knows the exact location she crashed into the Pacific or even how close she was to Howland Island when she ran out of fuel.

It's a big planet.

Most of it is covered in water.

There are many, many lost ships and planes.

It probably sunk in the Bermuda Triangle would be my guess.
