This book introduces the ShuttlePlane as the world's next Human Transport, and it is believable. Thank goodness there is finally hope...believable hope. The reason the book is pricey is because it has to have the highest esteem on the shelf if it is going to be of value. People either believe and they pay the price (and are also more likely to read the book and have the book as a symbol of that belief), or they do not believe, and do not contribute. We at ShuttlePlane have a vision...we know it will be supported. Giving ShuttlePlane corporation an economic push to get the 's_plane' built is what the $64 dollar contribution each of us sacrifices today is all about. And, making this commitment is going to benefit everybody tomorrow with a human transport that is: green, equal, safe for passengers/pedestrians, quiet, fast, steam-cleaned, demand-available, point-to-point with no-traffic. So if you are a believer, and someone that wants to get the ShuttlePlane built...buy the book and bring it to 50th Earth Day 2020 in Oakland, CA on 20200422 (or any EarthDay in your area). Bring the book and hold it in the air and say, "ShuttlePlane, let's build it!" We need a million people at this event...all with green books costing 64 bucks each...then, because of the known sacrifice that each of us has made....people will know we are serious about getting the ShuttlePlane built. "Be careful of your actions they become your habits." "Be careful of your habits...they become your destiny."
