Grapevine

BREAK A LEG, MR. AMBASSADOR. William Walker, 53, had been ambassador to El Salvador only a few weeks when he decided to throw himself into his new job -- literally. Though he had no previous experience as a parachutist, the gung- ho diplomat recklessly accepted U.S. military trainers' assurances that a 10,000-ft. jump out of a C-130 would be a lot of fun. The Ambassador is now recuperating from multiple fractures in his leg.
