Sikhote-Alin meteorite

An iron meteorite fell on the Sikhote-Alin Mountains, in southeastern Siberia, in 1947. Though large iron meteorite falls had been witnessed previously and fragments recovered, never before in recorded history had a fall of this magnitude been observed. An estimated 70 tonnes (metric tons) of material survived the fiery passage through the atmosphere and reached the Earth.^[2]
