In what may turn out to be one of life's biggest unexplained mysteries; a pilot witnessed a collection of red glowing lights beneath him, just twenty minutes after a lightning bolt appeared to shoot up from the surface.
This incredible series of events took place south of the Russian peninsula Kamchatka and were witnessed by Dutch pilot JPC van Heijst and his co-pilot as they flew their Boeing 747 to Alaska.
While there's no official explanation for the event there has been some speculation that it may have been a massive underwater explosion caused by a volcano deep beneath the sea.
While that may explain the lights it certainly doesn't explain the lightning. There had been no reports of thunderstorms in the area and according to van Heijst the conditions they were flying through were not conducive with the appearance of lightning.
Then of course there's the small matter of the fact that both pilots saw the lightning shoot up into the air, not down towards the ground.
Sadly it looks as though the Norse god Thor isn't to blame, instead there are proven instances of huge volcanic eruptions actually producing their own lightning.
This only happens in the largest of eruptions and there's no real proof that in fact it can even be caused by an underwater volcano so while that's our best explanation for the moment, it certainly isn't definitive.
