We are about to start our journey to the end of the world. I know you'll be sat reading this, nudging the person next to you saying "aye up, he's lost the plot this time", but no, I'm not about to join the Flat Earth Society, nor will I be knocking on your door asking you to repent as the end of the world is nigh! We are flying from London to Ushuaia which is on the southernmost tip of South America, the self styled most southerly city in the world and 'Fin del Mundo'. From here we will board our ship, the Magellan Explorer which will take us to the South Shetland Islands and Antarctica
