The Sikhote-Alin meteorite that fell around 10:30 local time on February 12, 1947 in the Silkhote-Alin Mountains in the Soviet Union is the largest meteorite to fall in recorded history.  It was an estimated 70 metric tons, that survived the passage through the Earth’s atmosphere.  The large fireball was described as brighter than the sun, and from the north and fell at a 41 degree angle.  The flash and sound was heard for 190 miles.  The 20 mile smoke trail remained in the sky for several hours.

When it hit the atmosphere it was traveling at 8.8 miles per second.  At 3.5 miles up the meteorite broke up.
