No one knew where this US Navy boat disappeared to. A year later it was found 3,300 miles from...

The unmanned vessel was lost 75 miles off the coast of Norfolk, Virginia during a missile test and evaluation exercise last September, Timothy Boulay of the Naval Air Warfare Center Aircraft Division in Maryland told CNN in an email.
So how did the boat survive over 3,300 miles across the Atlantic Ocean? The foam-filled boats were designed not to sink, Boulay said.
This is the second time in 15 years that a boat has gone missing at sea, according to Boulay. He said the first was eventually found in the Dominican Republic.
"Our Atlantic Targets and Marine Operations team followed their established procedures, searched for the unmanned vessel for five hours, and then notified the US Coast Guard regarding the hazard to navigation," Boulay said.
