Gordon goes to Heathrow. Airplane crashes. Lands in India. Bombay Stock Exchange has record all time losses falling 15%. Returns to London, London Stock Exchange crashes. When he first became PM, God punished the people of England with floods, pestilence and Islamic fires of terror. Every national sporting event he visits, the home team loses. God must really hate Gordon...
I think you'll find one of the current popular theories is that of water contamination in the fuel causing icing in the fuel lines and subsequent fuel starvation to the engines.
I find it highly unlikely that any countermeasures would bring an airliner down. Besides, the autopilot continued to fly the aircraft once the engines began losing power - probably the only reason the aircraft made it down safely.
I don't think water in the fuel will have done it
Water is always in fuel but so is FSII (fuel systems icing inhibitor) which is in effect anti freeze
I was always told that water would burn off and the only thing it would do would be to reduce the range (if you load 21000 gallons of fuel and half of that is water you only have half the fuel you need)
Therefore if the water theory is correct it ran out of fuel which would fit with the engines shutting down
There is a fungi that can grow in the ground tanker which if it got into the aircraft would block fuel pipes but this is unlikely unless the chinese are way off there game
The water if it was going to freeze would have froze at 35000 feet when it was -40 not once it came down from altitude into warmer air
I do like the thought though of Gordon Brown driving across London and aircraft in the holding pattern falling 500 feet or so as he went under then restarting and climbing back up
How tempting would it be if you where his driver just to flick it on as he went overhead and create another larger 'Munich' type crash
