Its official name had been changed to Ronald Reagan Washington National Airport, but to the locals it would be forever simply National. Finn parked in one of the lots near the main terminal building, whose chief architectural feature was a series of connected domes copied from Thomas Jefferson’s beloved Monticello. Bag in hand, he trudged across a skywalk into the sleek interior of the airport. Inside a restroom stall he opened his duffel, pulled on a heavy blue jacket with reflective stripes on the sleeves and a pair of blue workpants, slid a pair of orange noise mufflers around his neck and clipped the official-looking ID badge onto his jacket.

Employing a standard turnstile crash maneuver, he inserted himself into a herd of airport employees trekking through a “special” security line. Ironically, this line lacked even the cursory level of scrutiny forced on ordinary passengers. Once on the other side of the barrier he bought a cup of coffee and casually followed another airport worker through a secure door to the tarmac area. The man actually held the door open for him.

“What shift you working?” Finn asked the man, who told him.

“I’m just coming on,” Finn said. “Which would be okay if I hadn’t stayed up for the damn football game.”

“Tell me about it,” the man agreed.

Finn skittered down the metal steps and walked over to a 737 that was being prepped for a short-haul flight to Detroit with continuing service to Seattle. He passed several people along the way, including a fuel man, two baggage loaders and a mechanic inspecting the wheels of the Michigan-bound plane. No one confronted him because he looked and acted as though he had every right to be there. He made his way around the aircraft as he finished his coffee.

He next walked over to an Airbus A320 that would be on its way to Florida in about an hour.
