For those who find the 'rumour' nature of this website distasteful, you would be better viewing elsewhere. This is a rumour website and that is therefore what you get!
There is an interesting 'eye-witness' account from a Dutch journalist on CNN who claims to have spoken to a number of passengers. They apparently described some turbulence (stall?) immediately prior to impact and all believe the aircraft ran out of fuel. Even though the passengers are clearly not 'expert witnesses', they were nonetheless very close to the event and their views are certainly ones that attract my attention.
There are, of course, many reasons why the crew could have faced fuel starvation, if indeed they did. It should be pointed out that if fuel starvation in some form turns out to be a factor here, I am not in any way ascribing blame to the crew. Many crews have faced challenging situations like this and it may transpire that they did very well in getting the aircraft down at all.
