What was Lost is Found

The crew of the Phoenix has had little luck finding any sign of the bio-signature for the defiled but what they do find is a crashed Romulan D7 and the remains of an old Constellation Class ship, the USS Granger, that had been reported missing near the Romulan Neutral Zone on SD 7396 (2271).

How did vessels from over 100 years in the past get 200 light years from where they were.
