Little more than a century after the Wright brothers launched a gas-powered airplane from a sandhill outside Kitty Hawk, a team of Swiss explorers took off Sunday for their own run at aviation history, in a plane fueled only by sunlight. Strapped into the cramped, single-seat cockpit of a plane called the Solar Impulse 2, former fighter pilot André Borschberg lifted off just after 10:30pm EDT, Sunday from a military airport near the Strait of Hormuz and began the first leg in a quest to fly a solar-powered craft around the world.
