Well, hope springs eternal. History shows the federal government spending gobs of tax dollars on previous Boeing High Speed Aircraft projects when Boeing was still mighty and highly respectable - not one was built. A ground handling iron bird was built and tested at Moses Lake during the HSCT project (early to mid-90's) but it was hardly high speed, let alone hypersonic.
I hope tax dollars - direct funding or generous tax breaks - are not expended (wasted) on this project. This what a hypersonic flight experience would be like - a few hours airborne - and more time than that in the terminals at departure and arrival. I'd rather see effort expended in making significant improvements in the airline terminal experience.
There's likely to be much more hype than hypersonic flight coming from this.
