The computer age brought avionics - systems to control planes that humans could never fly. These systems, combined with new materials, designs and paints, as well as the unwavering commitment and singular vision of men like Skunk Works' Ben Rich, gave rise to the most recent revolution in military aviation - stealth planes that are all but invisible to enemy eyes. Like the jet engine before it, stealth technology has transformed warfare, and together with ever-advanced precision ordnance and purely autonomous planes, has positioned the world's most advanced air forces for a future where in-cockpit pilots may no longer be necessary.
