A cargo plane with a two-man crew crashed Tuesday in Alaska, and the pilots are believed to have died, US authorities said.

The crash of the plane happened in the morning, around 10:00 (local time), near the airport of Fairbanks, a city in the central part of this state, on the northwestern tip of the American continent, the Alaska police explained in a statement.

The plane had “two people on board” when it crashed “into the Tanana River” less than ten minutes after takeoff, he said.

“The plane crashed on a steep hill on the river bank and caught fire. No survivors were found,” the police said.

A photo of the crash site released by authorities shows burning vegetation on the bank of an ice-covered river, amid which is extremely inconspicuous wreckage.

The plane was a Douglas DC-4 type. Originally built as a US Army transport during World War II, the four-engine propeller-driven aircraft has been out of production for over thirty years. The few samples of it in the ethers today are mainly used for cargo transport.

The aircraft was on a fuel transfer flight, the National Transportation Safety Board (NTSB) confirmed. This federal agency will lead the investigation into the crash that has begun.
