Alan,
Good selection of aircraft - particularly like the flying boats/sea planes screen-shots.
Reminds me of the time I flew in one in Queensland, Australia out to the Great Barrier Reef to do some snorkeling. I was fortunate to be seated in the co-pilot seat during the short flight - just as we were about to land in a very calm stretch of water close to the reef, you can imagine my surprise when the pilot pushed the canopy back and stood up during the final landing stage, exclaiming that he needed a better angle of view to judge where the surface of the exceptionally calm water was!
