Two young brothers launch model boats to circumnavigate Antarctica

Two brothers from Aberdeenshire have built model boats that they hope will circumnavigate Antarctica. Ollie and Harry Ferguson, 13 and 11, were inspired by the Ross expedition of 1839-43, which led to the discovery of the Ross Ice Shelf. They built one metre-long replicas of HMS Erebus and HMS Terror,…
