Just back from a week’s expedition to survey the wrecks of the two K-class submarines K4 & K17 lost during the so-called Battle of May Island in the Firth of Forth on 31 January 1918. Amazing dive team – who gathered a vast collection of amazing video and stills – from which we are now processing 3D photogrammetery models of each submarine. More on that to follow!
