The big airlines of this world did not really keep up with time. They still use radar systems to plot there course and that while even the kids on the playground have GPS in their Cell Phones.
What would happen if airlines would change to to a GPS based system?
An Associated Press analysis of federal and industry data found that if the new system were already in place, airlines could have saved more than $5 billion in fuel this year alone. (only based on US airlines).
Oh man that means we could have saved 5 billion dollars worth of fuel and what would that have done to our planet. 5 Billion dollars could save you a lot of green house gasses. And it could be even enough to maybe make your fuel bill a couple of cents lower every time you go to the pump.
Why or why are airlines stupid enough to remove the Video entertainment system from their planes to save fuel while a simple GPS solution would have saved them a bundle.
