I have simple challenge for you. Make a working seaplane (must be ambhibia to start from runway). It can be a flying boat or floatplane or any kind of seaplane do you invent. I suggest to use MK3 fuselage to make a floats or body of flying boat and place wings and engines above the crew hatch (like this pl.wikipedia.org/wiki/wodnosamolot 2'nd graphic). On screens (or beter - video) show the start time, landing on water and 2'nd start from water. I did not succeed. Below you can see my attempts from 0.15.2. http://imageshack.us/photo/my-images/812/ksp2012081515370336.png/ http://imageshack.us/photo/my-images/21/ksp2012081515361520.png/ Sorry for my english im lernig it only a very short time.
