Fukushima - Is it a bird, is it a plane...or is it a luminescent mutant bee swarm mimicking a UFO?
The strange aerial formation was spotted high above Fukushima's tsunami-ravaged nuclear power complex during Wednesday's eclipsed full moon penumbral phase.
Japanese astronomers said today the flight path appeared to trace the mathematical sign for 'infinity' and emitted an ultra high frequency sonic pitch when reaching trajectory apotheosis.
The findings have been subjected to an official NASA alpha-particle spectroscopy test (a method of counting using a sauce (sic) in a metal disk) which detected nearly five million fluorescent 'killer' bees making up the formation.
Additional full spectrum analysis also found the luminous sheen on the insects' wings may be some sort of synthetic coating, possibly from pollution or exposure to unidentified contaminants.
But the absence of a Queen Bee among the swarm has prompted some physicists to speculate that the phenomenon must have been composed purely from drones - worker bees on automatic pilot.
"They probably get the Queen's flightpath instructions before exiting the hive," a NASA Jet Convulsion Laboratory spokesperson speculated today.
"We'd love to know the location of the nest."
Earlier this month an oil tanker in the South China Sea reported navigation problems as a vast colony of 'Africanised' bees was found pupating inside the engine room.
The MV Aurora Borealis was briefly towed to port where the insects may have escaped before regrouping and taking flight.
The swarm has now vanished off the radar.
