Sixty-four minutes had passed when an incredulous and slightly air-sick Robert Langdon stepped down the gangplank onto the sun-drenched runway. A crisp breeze rustled the lapels of his tweed jacket. The open space felt wonderful. He squinted out at the lush green valley rising to snowcapped peaks all around them.

I’m dreaming, he told himself. Any minute now I’ll be waking up.

"Welcome to Switzerland," the pilot said, yelling over the roar of the X-33’s misted-fuel HEDM engines winding down behind them.

Langdon checked his watch. It read 7:07 A.M.

"You just crossed six time zones," the pilot offered. "It’s a little past 1 P.M. here."

Langdon reset his watch.

"How do you feel?"

He rubbed his stomach. "Like I’ve been eating Styrofoam."

The pilot nodded. "Altitude sickness. We were at sixty thousand feet. You’re thirty percent lighter up there. Lucky we only did a puddle jump. If we’d gone to Tokyo I’d have taken her all the way up—a hundred miles. Now that’ll get your insides rolling."

Langdon gave a wan nod and counted himself lucky. All things considered, the flight had been remarkably ordinary. Aside from a bone-crushing acceleration during take off, the plane’s motion had been fairly typical—occasional minor turbulence, a few pressure changes as they’d climbed, but nothing at all to suggest they had been hurtling through space at the mind-numbing speed of 11,000 miles per hour.

A handful of technicians scurried onto the runway to tend to the X-33. The pilot escorted Langdon to a black Peugeot sedan in a parking area beside the control tower. Moments later they were speeding down a paved road that stretched out across the valley floor. A faint cluster of buildings rose in the distance. Outside, the grassy plains tore by in a blur.

Langdon watched in disbelief as the pilot pushed the speedometer up around 170 kilometers an hour—over 100 miles per hour. What is it with this guy and speed? he wondered.
