About global warming:
I posted here about 5 years ago who believes it is true - I was pretty much alone. There are still a lot of pilots who wish to ignore. One proof more that pilots don't have to be very knowledgable. The numbers of ignorants will decrease. Let's hope that they don't use more fuel than necessary - the price of it will make them behave rationally...
