Wow, those Lun photos are amazing. I was really surprised at the complexity of the hull design, with all of it's steps and the retractable step. I also found the cockpit gauges informative. Especially the "artificial horizon" which apparently uses the water surface as the reference and has the strip gauges for height above the water on each side. I wonder if the height on each side was based off of wingtip height above the water? Perhaps it's in the text, but beautiful pictures of a very interesting WIG.
