Without publisher numbers this is all fantastical wish-thinking, but I was assuming only one class was taught each year at each school. Also, that the list I linked was exhaustive. I pointed out that the number of one-class per year schools could be more than doubled by included aeronautical programs, and probably increased ten-fold when you include flight schools, race-car dynamics courses, or even civilians that want to learn about a subject. I, myself, have purchased three different textbooks in the past year in order to become more informed about the area I work in.
In short, 5,000 seems low for this book. But let's take 5,000 as the number sold. That's $930,800 at the Amazon price. Let's say the publisher gets half, or $465,400. That sounds really good for a book that's on it's 5th edition, and so doesn't need anything more than typo revision and $10 an hour graduate problem solvers for the end of chapter stuff.
