Preliminary investigations have confirmed that a plane that crashed in the Colombian mountains last month killing 71 people including most of a Brazilian football team was out of fuel, officials said. The LaMia airlines charter flight crashed just outside Medellin on November 28, virtually wiping out the Chapecoense Real football club as they traveled to the biggest match in their history. <br/><br/>Freddy Bonilla, the head of Colombia's civil aviation authority, said investigations indicated the British Aerospace 146 jet had run out of fuel. Bonilla told a press conference in Bogota that the pilots were aware of the fuel limitations they had at the time adding that it was neither adequate nor sufficient. However, they did not sound the alarm until several minutes before the crash, he said.<br/><br/>According to the civil aviation authority, the pilots requested priority to land because of a fuel problem. They then began their descent before receiving authorization. At that time, one of their engines stopped. Three minutes later, all four were gone.<br/> <br/>The plane declared an emergency at 9:57 pm because of a "total electrical failure," then disappeared from the radar. At 9:58 pm, the plane slammed into the Cerro Gordo mountain at a speed of around 130 miles per hour, the authorities said.
