There is plenty of evidence regarding Admiral Byrd but when people read his firsthand testimony they dismiss it becouse they don't want to believe it. The fact of the matter is that Admiral Byrd was one of the most respected men in our military. This is one reason he was given the mission. You can research the diary itself or the speech's he gave or the interview and what he said as soon as he got to Chile but you'll probably dismiss it, regardless of the Admiral's integrity, becouse there's no "proof". Do you realize that the biggest secrets have no "proof". Thats why there secrets. We can piece together circumstancial evidence like his flight logs from Antarctica that shows missing time or the fact that some of the fleet never returned as shown by Army paperwork. Then there's the Russian General that defected describing a battle he witnessed in Antarctica involving American troops and flying craft he's never seen before. Firsthand testimony is considered proof but for some people that's not good enough.
