Point of No Return chronicles one of the most suspenseful and pioneering scientific adventure stories of the 21st century, following two pilots in their attempt to circumnavigate the globe in an airplane fueled exclusively by sunlight. Their mission: to prove the potential of clean technology and to inspire hearts and minds. To achieve their goal, they must push themselves and their team of engineers and meteorologists far beyond their limits. Thirteen years ago, Bertrand Piccard and André Borschberg began building what many experts said was impossible: a solar-powered airplane capable of flying day and night. With the wingspan of a 747 jet and the weight of a car Solar Impulse is extremely fragile; high winds or turbulence can snap the wings in two. But the 26,000-mile journey tests more than their technology. In an unheated, unpressurized cockpit, the 5-day solo flight across the Pacific Ocean becomes a feat of endurance unlike any other in aviation history. Technical failures, unplanned landings, and stormy weather put the entire mission in jeopardy and drain the spirits of the team. To succeed, both Piccard, a psychiatrist and balloonist, and Borschberg, an engineer and jet fighter pilot, must set aside their differences, and go against the advice of their engineers. Their gripping story sheds light on what it takes to attempt something truly groundbreaking and is testament to the tenacity of the human spirit.
