I heard that the chamber is 2 miles down, and is actually an abandon underground "alien" base, complete with disks.
LOL,ASE.......thanks for jarring the ole memory....
That reminds me,I saw a show years ago,they used ultra-sound to see if they could find any rooms or tunnels underground,that they haven't seen yet.
Well they did find some places that were hollow. But the Egyptian government would not let them dig,and made them stop. I have heard nothing about
it since.
Whether it has something to with aliens,I don't have a clue.But one way or another the Egyptian government is hiding something.
