25 most powerful people in business

Some are empire builders. Others are hired guns. But if they truly have world-class oomph, they're on Fortune's subjective - yet really quite accurate - list of the most powerful businesspeople in the world.

James McNerney
17. James McNerney
Chairman and CEO, Boeing

The global economy doesn't fly without aircraft, and Boeing has made about 75% of the world's commercial airplane fleet. The company is also a huge defense contractor, turning out a broad range of fighters, bombers, missiles, satellites, and a bunch of other stuff they could tell you about - but then they'd have to kill you. Adding to its global clout, Boeing sells to governments around the world. Think about it: McNerney runs the company that produces more airplanes than any other and that also knows the secrets behind some of the world's most fearsome military technology. That's power. --Geoff Colvin
