Question

One hundred years ago... "The Tunguska Event".. Which theory do you support?

Answer 1

I tend to believe the most logical of theories so asteroid.

Answer 2

uh-oh, the syndicate will get you b/c of purity control.

Answer 3

Object (comet meteor etc) exploding in the air above the site.

I favor this theory as some experimentation has been done that can duplicate the blast pattern found on the ground.

The trees in tunguska fell in a pattern that resembles a butterfly.     A scale model test was conducted using small match stick sized "trees" and various small scale explosive charges detonated in an effort to replicate the blast pattern.  

Test results show that a nearly identicat butterfly pattern could be produced with multiple explosives (to duplicate a hypersonic shock wave) suspended above the test board.
