Jerusalem - The US author and humorist first hinted at the extraterrestrial silo's existence during his 1867 travels around the Middle East.
Today the publication of aerial shots showing a 'massive subterranean matrix' under the 7th century AD Islamic mosque have upheld Twain's extraordinary comments.
The satellite imagery clearly debunks ancient Israeli counter-intelligence campaigns circa 692AD debunking the UFO silo's existence.
Twain roundly rejected Jewish spin doctors' rants.
These denied that remains on King Solomon's Temple - destroyed by Nebuchadnezzar II after the 587 BC Siege of Jerusalem - had been used in the silo's construction.
But documents outlining the anti-UFO campaign were found centuries ago in a secret archive buried under Moriah - a mountain described in the Book of Genesis as the setting for Abraham's intended sacrifice of his son Isaac.
Twain's diary entries condemned that subterfuge and relegated the Israeli cover-up to the dustbin of hystery where it rightly belongs.
'Everywhere ... whitewashed portions of pillars, curiously wrought launchpads, elegantly carved precious remains of Solomon's Temple... These have been dug from all depths and rubbish of Mount Moriah!'
A spokesperson for the Israeli Cultural Ministry said today "WTF??"
