The Story Behind the Longest Solo Flight in History - Men's Journal

What he saw was alarming: 105 degrees. And day by day he saw the number rise, eventually to an ominous 140 degrees. Borschberg had reason to be: His plane, the Solar Impulse 2, is powered entirely by those solar-charged batteries, and a loss of power would mean a slow descent and crash in the middle of the ocean. By the time the plane set down in Honolulu after 118 hours — nearly five straight days — it had smashed the record for the world's longest solo flight. It also became the first solar-powered plane to fly such a distance, more than 5,000 miles. "An airplane with no fuel can fly longer than an airplane with fuel. The plane — which has 17,248 solar cells covering its wings, tail, and fuselage — is the brainchild of Piccard. But he'd long held on to a fantasy of being able to "fly forever" via solar power. With Borschberg on board as his partner, Piccard set out on a decadelong journey to prove that the sun's energy could power a plane. To fly forever — or as close to it as possible — the plane would need to ascend to 28,000 feet during the day to collect solar energy, then slowly descend at night while running on battery.
