Young eagles is a great program. I have supported it for years. For a couple of hours of "study" they get a free airplane ride and maybe some stick time. Back up. I said a couple of hours of study.
Now, go to a restaurant, high school basketball/football game, swimming pool, beach or any public area. How many of those kids with their heads down in their cell phones are willing to put it down and invest eighty thousand dollars and three to six years building an airplane? General aviation started dying fifteen years ago. We didn't have the answer then and we don't have the answer now. Neither does Rutan or Vangrunsven.
