Paul, Nice try - you cant argue with the brainwashed. All I would ask is that people keep an open mind (thats how you learn new things), cast a wide net and dont watch TV. The Crisis News Network, Fox news and the others are simply about stimulating the amygdala (fear and loathing) and are all about catering to and growing their tribe (or herd) so they can sell stuff. If any of these folks on the thread bothered to understand the history and power of incentive prizes they would understand that we are using a carrot rather than a stick (remember the Orteig prize and the XPRIZE?) to accelerate through the barriers. But mostly they see the words “decarbonizing aviation” and dont bother investigating. They just attack at any perceived threat with kernels of truth tied to conspiracies. In intelligence and propaganda circles these are known as “useful idiots”. They fight hard on your behalf (who’s behalf?) to sow discontent, anger and further misinformation. Russia is the likely origin of many of these irrational claims and more than a few commenters here are likely Russian trolls whose mandate is to make us fight amongst ourselves. Everyone on this thread (should) have a love for aviation and a love for America. This makes all of us have much more in common than any of us do with Vladimir Putins view of the world. Instead of talking about issues with an open mind, and learning about their merits and potential problems and adapting new understandings and plans of action, we tear ourselves apart like jealous children over a coveted toy. Todays threats of civil war between the south and the north or the right versus left, or climate change versus denial? Its Putin talking. Meanwhile - we have important work to do, so arguing with unhinged, but perhaps well meaning patriots mixed with Russian trolls, gets us nowhere. I will go back to my work which includes professionals from the right and the left and manufacturers and charter operators and end users and national labs, first to learn all about the barriers to decarbonization and then to work on incentive prizes to accelerate the changes needed and hope that it will be meaningful in the end. It is a risk, but one in which I am willing to take to ensure the viability of aviation and our planet into the future. If they dont understand that rationale - thats on them.
