Seems that in Soviet Russia they had also an accident based on the actions that caued 9/11 tragedy.
Though in Russia it happened thirty-three years ago, in 1976.
Not much of Russian people know about that accident, it was not in Moscow or Saint-Petersburg but in rather small city of Novosibirsk, known as "Science City" - the place where a lot of Russia research centers were based in Soviet times. Even these days this city is said to be the leader in Russian offhore programming companies - tens millions dollars of offhore programing orders come there from all of the Western world.
So, back to what has happened in late seventies there. Actually it was the same scenario when man took the plane and crashed into the multistored building on purpose, with evil plans of kill and destruction in his mind.
