One example of this kind of space-crash-error incident I'm aware of is when the US deorbited Skylab, it didn't break up the way the models had predicted and several pieces, including multiple oxygen canisters (about the size of a refrigerator each) crashed intact into the Australian outback. Australia fined the U.S. for littering. The U.S. took one canister back, which is on display at the U.S. Space and Rocket Center in Huntsville, Alabama.
