SANTIAGO (Reuters) - The Chilean navy and marine scientists say they may have found Latin America's first submarine, a steel tube topped by cannons, which sank off the coast of Chile 141 years ago.
They say they have detected an object on the seabed in the Bay of Valparaiso, 90 miles (140 km) west of the capital Santiago.
This object, its dimensions, its position, the way it's facing and the depth it's at are all extremely similar to the characteristics of the Flach," they said in a statement.
The 39-foot (12-metre) vessel was designed in the 1860s by German immigrant Karl Flach and made several successful test voyages in 1866.
