A Russian passenger plane has gone missing during a demonstration flight near an Indonesian volcano.
Officials say the Sukhoi plane had 44 passengers and crew on board, including Indonesian business people and Russian embassy staff. Earlier reports spoke of 46 people on board.
Radio contact was reportedly lost shortly after take-off from Jakarta airport, as the plane was passing over West Java.
A government spokesman said the last that was heard was when pilots asked for permission to descend from 10,000 to 6,000 feet.
The Superjet 100 – Russia’s first new passenger plane since the fall of the Soviet Union – was on its second demonstration flight of the day.
A search operation by land and using helicopters near one of West Java’s many volcanoes failed to find the jet.
A spokeswoman for Russia’s United Aircraft Corporation said pre-flight checks had been “carried out in full and the plane was completely ready to fly.”
