If there is anything to this space engine story, which I think there is, the government does not let you fail. Money won't be a problem in production. WThe space programs already have a serious problem in that they do not even have rocket engines that can launch sattelites into space without buying them from Russia. The USA does not have the ability to crank out large rocket motors like the Saturn we used to make here in the US. So anything that will help the the space companies will start being pushed much more now than in the past, imo. Just another good aspect of APT
