To fly a jet fighter consumes a lot of kerosene and off course is not the best thing for the environment. And although we love flying our jet fighters, we are also very much aware of the problems of the environment and what we will leave to our next generation. This is why we have signed up with Action Carbone, an NGO managed by Frenchman Yann Arthus Bertrand, and our now making a contribution each time we fly. Basically, we compensate each flight by making a donation of 27 euros. It may not sound much, but this is still something and we are happy to do that. The next step would be for engineers to think about transforming jet engines so that they can work with bio fuel. Tests have been done with airlines such as Virgin, but progress has still to be made regarding military planes.
