Below, he could pick out his small house on the edge of one of Alcoa's parks. The steadily receding sight recalled disquieting emotions. Decker had spent most of his life traveling. As a boy it was with his family, moving from one army post to another. After that he had spent a year and a half hitch-hiking across the United States and Canada; then four years in the army, two in Vietnam. Partly he felt cheated: he had never really had a home. But partly he felt blessed. Decker hated leaving, but he loved going.

Decker's flight arrived late into New York and he had to run to make his connecting flight to Milan, Italy. Nearing the gate he looked for a familiar face but saw none. In fact, at first glance, there was no one at the gate at all. Decker looked out the window. There was the plane, but at that instant he heard the jet engines begin to whine. Thundering down the red carpeted incline of the jetway, he almost collided with a ticket agent.

"I've got to get on that plane!" he told the woman, as he put on the sweetest 'help me' look he could muster.

"You have your passport?" she asked.

"Right here," Decker answered, handing it to her along with his ticket.

"What about your luggage?"

"This is it," he answered, holding up an overstaffed and somewhat oversized carry-on bag.

The plane had not actually moved yet, so after notifying the pilot, it was an easy task to move the jetway back into place. After a quick but heartfelt 'thank you,' Decker boarded the plane and headed to his seat. Now he saw a sea of friendly and familiar faces. On his right was John Jackson, the team's leader. A few seats back was Eric Jumper. Both were from the Air Force Academy in Colorado Springs. Jackson had his Ph.D. in physics and had worked extensively on lasers and particle beams. Jumper, also a Ph.D., was an engineer specializing in thermodynamics, aerodynamics, and heat exchange. In fact, almost everyone in this sea effaces had a Ph.D. of one sort or another. Altogether there were over forty scientists, technicians and support people. Though he knew most only by sight, many paused long enough from their conversations to offer a smile of welcome or to say they were glad he had not missed the flight.
