Well, I should have known you'd know; what is it?
As for the tribes having some sort of ability to "know" something's coming,my guess is that like animals,they are so primitive,that they really are more like animals and are more attuned to feeling whatever animals do.Then,they could just be more sensitive to the way the animals behave and knew that something was coming.Six of one,1/2 a dozen of the other...take yer choice. LOL
The whole Duke stuff,no matter what they call each section,has to do with the paranormal.They've been studying this stuff for at least 70 years.
And the old USSR had teams working on this forward viewing stuff in the '50s,BTW.
Many witnesses over the centuries have reported that fireballs are accompanied by a low thunder-like noise coincident in time with the meteor flash. These sounds cannot originate acoustically since sound waves cannot not travel fast enough to be heard at the same time as the meteor flashes.
The best explanation for many of these simultaneous meteor sounds is offered by Colin Keay. He suggests the sounds arise by electrophonic transduction. The wake of the fireball traps its magnetic field which creates very long radio waves which travel at the speed of light. The radio waves engender audio waves by interacting with ground-level objects such as trees or spectacles. This is still a controversial idea even though the sounds have now been recorded by several researchers. The same principle may explain reports of auroral sounds, animal unease prior to earthquakes, and sounds heard prior to a nearby lightning strike.
The usual electrophonic explanation fails for some short duration "pops" and staccato "clicks" which accompany certain meteors. Luigi Foschini and Martin Beech suggest such short duration pulses are generated by a strong electric field across the shock wave propagating in the plasma formed by the catastrophic disruption of the meteoroid in the atmosphere.
