Duncan - Ian Kimm appears to blame the aircraft industry for the "high level" of CO2 emissions. This does follow the logic of many who blame the oil industry or pipelines for vehicle emissions. Perhaps that should be the fault of the auto industry instead!
Obviously by the same logic electric companies are to blame for power generation emissions!Ready for realism? Check the mirror - turn on the light to get a good look. Who is it who requires transportation or power and ask where does this energy come from that I use/need daily without thought? Ugly answer?Seriously this can be "fixed" but recognizing a problem's source must be a first step. And by the way, look up electric airplanes - by Air Bus!Bob ConibearDuncan
