meteors are hitting the earth all the time, at a microscopic level, but the bigger ones you see usually come during meteor showers.
a REALLY big one hit in1908 in Tunguska, Russia in the Siberian Arctic.
I found this:
IF IT had hit Central London, Britain would no longer have a capital city. The force of the meteorite that hit eastern Siberia last September destroyed 40 square miles of forest and caused earth tremors felt 60 miles away.
An expedition from Russia's Kosmopoisk institute has only recently reached the site in a remote area north of Lake Baikal because of bad weather and difficult terrain, the Interfax news agency said yesterday.
Fragments of the meteorite had apparently exploded into shrapnel 18 miles above the Earth with the force of at least 200 tonnes of TNT.
At the time, Russian media reported that villagers 60 miles away had witnessed a gigantic fireball screeching down from the sky, causing windows to rattle and house lights to swing as they were hit by blast waves on September 25. There were no reported casualties.

Small meteorites fall to Earth all the time. Most of the time, they are reduced to nothing more than dust as they pass through the atmosphere. I seem to recall hearing about a large bolide or visible meteor that made a loud noise as it passed overhead in Canada during the last year, but I don’t know if it was ever found.
You can actually leave a table covered with duct tape, sticky side up, outside during meteor showers at certain times of year, and find microscopic traces of meteor dust on it. They did articles on this in Scientific American years ago. Try searching on collecting meteor dust, and good luck. Also, in some rock and mineral shows, you can get pieces of meteoritic nickel/iron.

Scientists Find Signs Big Meteor Hit Earth 3.5 Billion Years Ago
A large asteroid or comet, the kind that could kill a quarter of the world’s population, smashed into the Indian Ocean 4,800 years ago, producing a tsunami at least 600 feet high, about 13 times as big as the one that inundated Indonesia nearly two years ago. The wave carried the huge deposits of sediment to land.

The last one which is recorded as having been big enough to leave a crater (although not a very big one, only 27 meters across) was in 1947, and is named the "Sikhote Alin" impact site. It is near the eastern coast of Russia, approximately at latitude 46 deg North and longitude 135 deg East.
