In 1862, ambitious scientist James Glaisher set out to do the impossible: ascend higher into the skies than ever before. A pioneer of weather forecasting and of photography, he wanted to take ground-breaking research measurements from different altitudes. Before aeroplanes, the only unpredictable available method of air transportation was the hot air balloon. This is his memoir, detailing death-defying air ballon journeys in his own words. Soon to be a movie starring Eddie Redmayne as Glaisher.
