Weapons, based on “other principles” headache?
Try chinese weapons, based on “other principles” ,that is sound weapons principles.
Maybe method used in the destruction of the meteorite over Chelyabinsk?
The video shows another object following the meteorite at the same speed, right?
Which object may be armed with a Russian kinetic weapon?
But maybe it is also armed with Chinese acoustic weapons, given the long-term Russian-Chinese cooperation in the past?
But I don’t know, only possible scenarios and speculations…
Afterall we are just a musicians… 
Harpist of all things instrumental music players!
Pleasant to the human ears, but none the less deadly if …well…use your imagination!
