This is a book about one of the first recorded pilgrims who climbed Mount Sinai; it's about Amelia Earhart, the famous American aviator whose story and disappearance continues to capture the world's imagination. It's the story of a doomed expedition to discover the North West Passage, and the tale of Marco Polo, who remained at the court of the Kublai Khan for an incredible 17 years. The 50 Greatest Explorers in History brings to life the pioneers in aviation flying thousands of miles with the most basic of maps in open cockpits, exposed to the elements and the unrelenting smell of petrol fumes. They travel by steamboat, on horseback, by rickshaw, motorbike, train, swim with piranhas, embark into black nothingness in new spacecraft, explore by Jeep, yachts, tea boats and elephants, disguise themselves as men, take canoes and use innovative, advanced technological scuba equipment. Going where in many cases, no man or woman had ever gone before, some women featured in this books were often denied respect, acknowledgment, or recognition and they determined to break the 'men's club' mentality of global exploration from which they were excluded.
