Weather conditions appear likely to come under the scrutiny of investigators probing the helicopter crash that killed former NBA superstar Kobe Bryant, his daughter and seven others near Los Angeles on Sunday, when overcast skies and fog grounded other aircraft.
Bryant's Sikorsky S-76 chopper slammed into a steep hillside outside the town of Calabasas, California, about 40 miles (65 km) northwest of downtown Los Angeles, igniting a brush fire and spreading debris over a quarter-acre (1,000 sq. meters) of grassy terrain.
Hours later, Los Angeles County authorities said all nine people aboard the helicopter died in the crash.
