Working from exclusive inside reporting, New Yorker writer Nicholas Schmidle tells the remarkable story of the test pilots, engineers, and visionaries behind Virgin Galactic's campaign to build a space tourism company. Schmidle follows a handful of characters--Mark Stucky, Virgin's lead test pilot; Richard Branson, the eccentric billionaire funding the venture; Mike Moses, the grounded, unflappable president; Mike Alsbury, the test pilot killed in a fatal crash; and others--through personal and professional dramas, in pursuit of their collective goal: to make space tourism a reality.
