A so-called base flyer, left, and a base jumper descend from the roof of the Park Inn Hotel in Berlin, the city's tallest. The new, base-flying attraction allows adventurous participants, after being strapped into a harness that's attached to a cable and winch, to step off a platform and experience near-free-fall speeds in a controlled descent down the face of the building before brakes bring the ride to a stop just before the rider reaches the ground. The hotel also has launch platforms for base jumpers, who ride parachutes to terra firma rather than wires.
