Up close the airplanes were larger than she would have imagined. She looked up at the dark windows, the curve of wings. Impossible to imagine that machines so enormous had ever taken to the air. Clark walked slowly. She saw the cat again, running fast and low at the base of the air traffic control tower, heard the squeak of a rodent when it pounced. The tower’s steel door opened, and she found herself in a small room where a guard kept watch through a peephole, candlelight glinting on elevator doors. The door to the stairwell was propped open with a rock.
“It’s nine stories,” Clark said. “I’m afraid this may take some time.”
“I’m not in a hurry.” It was peaceful, climbing the stairs with him. He seemed to expect no conversation from her. A slow ascent between shadowed stairs and moonlit landings, the tapping of his cane on steel. His breathing was labored. At every landing they stopped to rest, once for so long that Kirsten was almost asleep before she heard him pull himself up on the railing. The dog lay down and let out a theatrical sigh at each landing. There were open windows on every floor, but there was no breeze that night and the air was hot and still.
“I read that interview you gave a few years back,” he said on the sixth floor.
“That newspaper in New Petoskey.”
“Yes.” Clark was mopping his forehead with a handkerchief. “I want to talk to you about it tomorrow.”
On the ninth landing, Clark rapped a pattern with his cane on a door and they were admitted into an octagonal room with walls of glass and arrays of darkened screens, four people with binoculars watching the tarmac, the terminal, the shadows of the gardens, the barrier fence. The dog sniffed around in the shadows. It was disorienting, being so high off the ground. The airplanes gleamed pale under the stars. The concert in Concourse C seemed to have ended.
“Look there,” Clark said, “to the south. It’s what I wanted to show you.” She followed the line of his finger, to a space on the southern horizon where the stars seemed dimmer than elsewhere in the sky. “It appeared a week ago,” he said. “It’s the most extraordinary thing. I don’t know how they did it on such a large scale.”
“You don’t know how who did what?”
“I’ll show you. James, may we borrow the telescope?” James moved the tripod over and Clark peered through, the lens aimed just below the dim spot in the sky. “I know you’re tired tonight.” He was adjusting the focus, his fingers stiff on the dial. “But I hope you’ll agree this was worth the climb.”
