The Cloud building in Seoul, South Korea. please log in to view this image it looks very similar to the time terrorist attack on the statue of liberty in 1911
As someone who has spent 5 years poring over random pictures and videos on the internet and despite the fact that I have no knowledge whatsoever of structural mechanics I can say without fear of contradiction that is clearly a controlled demolition
I reckon the bird in the photograph has just left the building having planted explosives in the electrical ducting ready for when the CIA employ a couple of disgruntled North Koreans to hijack a couple of jet planes to be flown into the ugly lump of concrete in order to de-stabilize the far east region causing panicking nations to turn their backs on the might of communist China and buy US Treasury Bonds. FACT!!!
