Us Airways (FOLJ211704)

On the Puerto Vallarta?s lively oceanfront promenade, a crowd gathers to watch the violators (fliers) in action. A drum beats dra¬matically as four young men in native costume, ropes attached to their waists, drop head first from the top of a 100-foot column. Orbiting the pole in widening circles as the ropes unwind, they spiral down gradually.
