I know about the landing on the Hudson (my apartment faces the Hudson and I saw it happen), but this paragraph still didn't make sense to me. What solution did the pilots push? Sullenberger, the pilot on that flight is both a glider pilot and a GA flight instructor, so he seems to be the perfect argument that GA skills lend themselves to better problem resolution in unexpected flight situations: he was essentially landing a glider when both engines went.
