Blue is chairman and CEO of $2.7 billion (est. sales) defense company General Atomics. The company is best known as the manufacturer of the Predator drone, which was one of the first drones to fly over Afghanistan after 9/11. He and his brother Linden bought GA when it was a nuclear energy company in 1986. Three decades earlier Neil (left) and Linden (right), who are looking at a map of South America in this photo, raised $3,000 to fly a single-propeller Piper aircraft around the continent. The feat landed them on the cover of Life magazine. Neal Blue later served in the U.S. Air Force as a nuclear weapons custodian.
