RARE CRASH :Plane carrying Brazilian Soccer Team crashed because it ran out of fuel.

Colombian officials probing Monday's crash that killed 71 people including most of a Brazilian soccer team face one of the rarest types of accidents and perhaps one of the hardest for families to comprehend, amid reports that the airplane had run out of fuel.
U.S. investigators cited the crew's failure to manage fuel or declare an emergency promptly - two possible scenarios likely to be examined in this week's disaster.

Crew behaviour will not be the only focus. Recent probes in Ireland and elsewhere have shown that officials may probe deep into an airline's processes and operating systems and, if necessary, the relationship between companies involved.

"If it is confirmed that there was no fuel, then it will be asked why that happened. Was there a fuel leak? Was the amount of fuel placed on board the same as planned? Were there stronger headwinds than expected?" Hayes said.
