Indonesia teams scour ravine for clues in deadly Russian plane crash

Officials say search teams on the face of an Indonesian volcano are still looking for the black box recorder that could explain why a Russian-made jetliner crashed into the mountain.

The Sukhoi Superjet-100 had 45 people aboard when it crashed into Mount Salak on Wednesday during a flight intended to woo potential Indonesian airline buyers. All aboard are presumed dead and helicopters are ferrying remains to the capital for identification.

Top civil aviation official Herry Bakti Gumay says Indonesian and Russian investigators including professional climbers are searching for the black box in a ravine near where the plane's scattered wreckage was found.

The Superjet is Russia's first new model of passenger jet since the fall of the Soviet Union two decades ago.
