• David A. Kirwan, a 24 year old tourist at Yellowstone National Park, jumped into the alkaline (pH 9) and scalding (202 F) Celestine Pool to save his dog. The dog died within moments and its body dissolved in the hot spring. Kirwan, burned over his entire body, was airlifted to Salt Lake City and died the next day.
• Martina Navratilova became an American citizen at a ceremony in Los Angeles. Until then, the women's tennis star, who had defected from Czechoslovakia, had lived in fear that she would be kidnapped and returned for trial.
