On the 12. Febuary 1947 at 10:38 am, eyewitnesses in the Sikhote-Alin region of eastern Russia, observed a bright flash in the sky, followed by a fireball brighter than the sun descend from the atmosphere. The resounding boom could be heard as far away as 300 kilometers from the impact site. This event would prove to be the biggest meteorite strike of it´s kind in modern history, attracting the press and scientists eager to examine the visitors from outer space.
Researchers have calculated that the meteors was travelling at approximately 52,000 km/h when it collided with Earth´s atmosphere. This would have left an estimated 32 km long smoke and vapor trail in the sky for a number of hours after the strike.
The impact left over 120 crates of varying size, between 0.5 and 26 meters diameter, in an area measuring 4x12km
