I have no idea I'm afraid, Tom 775257. Why do you ask?
I am pleased this debate has moved away from the politics though.
I just had a simply thought, what if you could do away with all tankering within Europe?
Some experts are talking about we only have ten years left before we do ireversably damage to the planet. (please no comments on how true this is.)
Thousands of tons of fuel are burnt every year for no other reason than a monetary gain, surely there must be a better way.
I have limited brain cells left after burning so many out in ground school which is why I have thrown the question open to the pilot world.
I am not bold enough to suggest the idea could or couldn't work but I think it's worth debating.
Carry on..............
