The Moth and the Mountain by Ed Caesar

In the 1930s, as official government expeditions set their sights on conquering Everest, a little-known World War I veteran conceived his own crazy, beautiful plan. He would fly a Gipsy Moth aeroplane from England to Everest, crash land on its lower slopes, then become the first person to reach its summit - by himself. Maurice Wilson didn't know how to climb.

He barely knew how to fly. But he had pluck, daring and a vision - he wanted to be the first man to stand on top of the world. Wilson is a man written out of the history books - dismissed as an eccentric and a charlatan by many, but held in the highest regard by many mountaineers.

The Moth and the Mountain restores him to his rightful place in the annals of Everest and in doing so attempts to answer that perennial question - why do we climb mountains?
