Apparently on April 17, 1897 a UFO crashed in Aurora, Texas. This was a few years before the wright brothers flew their first flight. There were apparently multiple reports of a body recovered and buried in the Aurora Cemetery. Apparently a headstone depicting a flying saucer once marked the site, but that has since been removed.
Private investigators such as MUFON and UFO Hunters have tried to get permission to exhume the site, but it was never granted. However ground penetrating radar apparently does still reveal remains of some sort at the unmarked grave.
I believe most people are ready and believe that Aliens may exist, and don't understand the reason for keeping any knowledge of them hidden if it is being hidden. And if not, then why not allow this to happen?
