Sandringham, Norfuk - (X-Files): Earlier this week the ominous craft was seen terrorising the drunks running the Kremlin.
This weekend the massive pyramid scheme UFO has been spotted above Sandringham House, sucking flatulent greed house gases from the puppet monarch's private quaters.
"That's how the aliens refuel their ponzi-scam craft," NASA professor of retroengineering Dr V Smartt said today.
"The propulsion system feeds off cyanide vapors. And the biggest natural source of these? Right here up the old cow's majestic arse."
The craft's sighting does not seem to be bothering the MoD which officially mothballed UFO probes earlier this year.
A spokesman for the UK's National Poisons Unit commented this morning that with a bit of luck horrid old Mrs Joseph Ratzinger would croak it in time for Christmas.
"There's only so much cyanide depletion a withered old rattlesnake like Queen Elizabeth can actually take."
Landfill sites are on standby ahead of any early cremation.
