History was made Tuesday when Prime Minister Stephen Harper announced that one of the missing 1845 Franklin Expedition ships was found.

This week's video shows some of the first underwater footage of the shipwreck discovered in the Queen Maud Gulf. The discovery was made during this year's Victoria Strait Expedition, a flag expedition of The Royal Canadian Geographical Society. This was the sixth exploration mission in six years looking for the missing ships, HMS Erebus and HMS Terror. It's still not known which of the two ships was found.
