On that questionable photo of someone resembling Amelia Earhart, which appears to have been easily debunked:

Kota Yamano, a Japanese military history blogger, was skeptical about the photo as well. Shortly after learning about it, he searched the term “Jaluit” in the National Diet Library and quickly found the photo in a 1935 book. The whole thing took about 30 minutes, he said.

“I wonder why (the) History Channel did not have even one person who understand Japanese or the history between Japan and (the) US,” he told CNN.

Simple: They had something exciting to show on TV and wanted ratings. People like this see something intriguing and start salivating, neglecting to do even the most obvious research.
