An “SOS” note scrawled in the sand actually worked for two stranded women in Hawaii. A tour helicopter noticed the letters and notified naval aviators who were training nearby; they saw the inscription and flashes from a mirror and sent a helicopter and swimmer to pick up the stranded pair, one of whom was ill and injured, the AP reports. Both were hospitalized. There had been a downpour the night before in the area, which can only be reached on foot or by water, said a Kauai official. (More Hawaii stories.)
