404, perhaps if the airlines took a holistic approach to the funding of this the industry would be much better resourced. In the past airlines took their pilots from GA, a pilot in GA flying WAAS like approaches would be trained on them by the time they reach the airlines (ahh have a dream!). Ain't going to happen I know while scumbags like Joyce are around..........
