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, and a founding member of the Royal Meteorological Society, he wanted to take ground-breaking research measurements from different altitudes.

On 5th September, along with experienced balloonist Henry Coxwell as his pilot, he lifted off in a hot air balloon for what would prove to be a death-defying and historic flight. Rising above the English countryside, they rose to the remarkable height of 37,000 feet (7 miles or 11km), almost killing both men, who experienced blurred vision, loss of motor function and, eventually, unconsciousness. It was a miracle they survived to tell the tale.

Written in his own words, The Aeronauts chronicles Glaisher's incredible flights and discoveries first hand, as well as his observations on those pioneers who came before and inspired him. His audaciously daring journey forms the story of the forthcoming major motion picture The Aeronauts.
