Chapecoense plane crashed due to lack of fuel, says airline

"The plane should have refueled in Bogota," but instead bypassed the Colombian capital and headed straight for its destination Medellin, Gustavo Vargas, a representative of airline LAMIA, was quoted as saying in Bolivian newspaper Pagina Siete.

"The pilot was the one who took the decision not to enter (into Bogota for refueling), because he thought the fuel would last".

Colombian authorities are investigating what made the plane crash in the mountains of northwest Colombia on Monday night.

The crash killed 71 people including most of the Chapecoense football team from Brazil. Six people including three players miraculously survived.

Announcing the disaster on Monday night, the aviation authority said the plane reported electrical problems just before the crash.

But a Colombian military source told 'AFP': "It is very suspicious that despite the impact there was no explosion. That reinforces the theory of the lack of fuel".

Brazilian media said the plane's fuel capacity may have been inferior to the amount required for the distance of its journey from Santa Cruz in Bolivia to Medellin.

Colombian media, citing investigators, said the plane may have had to wait for another flight to touch down in Medellin before it could land.

Colombian broadcaster 'W Radio' aired a recording of what it said was the captain of another aircraft who said he had heard the pilot of the doomed plane over the radio reporting fuel problems followed by an electrical failure.

British, Bolivian and Brazilian investigators headed to Colombia to help with the probe, authorities said.
