Viewing Titanic with the latest technology

New technology is giving us the clearest view ever of what Titanic looks like as she rests on the ocean floor. The first full-sized 3D scan of the shipwreck has been captured through the use of photogrammetry. It's hoped this will shed new light on exactly what happened to the liner as it sank 3,800 metres down into the Atlantic in 1912. Mark Leishman spoke to Parks Stephenson, director of the USS Kidd Veterans Museum and long-time Titanic analyst.
