Jayapura: Indonesian officials say the black box has been recovered from passenger plane that crashed in a remote area of the country, killing all 54 people on board.
The plane went missing two days ago but rescuers only reached the crash site on Tuesday because of delays caused by the weather and rough terrain.
They said Tuesday that the plane was destroyed in the crash and there was no chance of any survivors.
There was no immediate news on the fate of 6.5 billion rupiah ($470,000) that were being transported by the plane in cash, intended for distribution to poor families as social assistance funds.
Thick fog and rain had hampered attempts by more than 250 rescuers and 11 aircraft to reach the wreckage on Monday, and they had been forced to turn back.

The disaster is just the latest air accident in Indonesia, which has a poor aviation safety record and has suffered major disasters in recent months, including the crash of an AirAsia plane in December with the loss of 162 lives.
The Trigana plane crashed as it flew from Papua's capital Jayapura to Oksibil, a remote settlement in the mountains to the south.
The plane lost contact with air traffic control about 10 minutes before reaching its destination, soon after the crew requested permission to start descending in heavy cloud and rain to land.
Officials suspect bad weather may have caused the crash.
Relatives of passengers waiting at Jayapura airport have become increasingly frustrated at the lack of hard news since the weekend, with some shouting "We want confirmation!" and throwing a table at a crisis centre in angry scenes on Monday.
Small aircraft are commonly used for transport in remote and mountainous Papua and bad weather has caused several accidents in recent years.
Last week a Cessna propeller plane crashed in Papua's Yahukimo district, killing one person and seriously injuring the five others on board. Officials suspect that crash was also caused by bad weather.
Trigana Air, a small domestic Indonesian airline, has experienced a string of serious incidents and is banned from flying in European Union airspace.
Last year's AirAsia crash was one of two major air accidents that Indonesia has suffered in the past year alone.
In June, an Indonesian military plane crashed into a residential neighbourhood in the city of Medan, exploding in a fireball and killing 142 people.
The aviation sector in Indonesia is expanding fast but airlines are struggling to find enough well-trained personnel to keep up with the rapid growth in the archipelago of more than 17,000 islands.
