A band of modern-day adventurers will re-enact Shackleton's historic Antarctic expedition of 1916. They will set sail in a replica wooden whaler and limit themselves to early twentieth century technology to recreate the original expedition. The replica has been launched by his granddaughter Alexandra Shackleton. Rob Murphy reports..
