By John S. McClenahen In the highly competitive aerospace industry, Seattle-based Boeing Co. has been quietly broadening its business base beyond aircraft production and satellite launches for more than a year. This week the Boeing board in effect told management to give even more attention to three promising business-growth ventures. Connexion by Boeing, which will provide air travelers with high-speed Internet and entertainment links, will be headed by Scott Carson, who becomes a Boeing senior vice president and will report directly to the office of chairman and CEO Philip M. Condit. John Hayhurst will be a Boeing senior vice president and president of Air Traffic Management, a business being established to put more technology to work in air traffic control and airport operations management. And James Palmer, already a Boeing senior vice president, becomes president of Boeing Capital Corp., the aerospace company's growing financial services unit. Both Hayhurst and Palmer also will report directly to Condit's office. "To maximize the value of three exciting growth opportunities for Boeing, we are creating new business units and setting up the leadership structure, business teams, and resources to ensure they succeed," says Condit. "These actions represent the energy and velocity of the Boeing Co. today as we pursue our three-fold strategy of running healthy core businesses, leveraging our strengths into new products and services, and opening new frontiers."
