For a while now I have been collecting excellent designs, artwork and photos from Scott Lowther's excellent Aerospace Projects Review Blog.
Plans and so on for many amazing flying things I remember reading about can be found on Scott's site, including spacereaft. You relaly have to see some of these designs to beleive them.
 In other posts I have commented on how preposterous fictional aircraft and spaceships annoy me because they don't even look like they would work: well, if you really want to make something that at least LOOKS like it would fly, check out the designs here, from real Aerospace companies.  I have just become a sponspor for Scott and it's worth it if you are a fan of all that sort of thing: for $5 a month you get all the goodies, actually a better deal than paying for each item alone.

This is the RYNO and it is real. Yup. The only problem is that you can't drive it legally faster than a segway even though it is capable of a lot more. The bar at the front is so you can tip it forward and rest the bar on theground when it is parked. It runs on batteries and (of course) has stabilising gyros.
About the only thing more awesome would be to have a model that folded into a small, hand-carry package.  . . . . but then they are probably working on that right now.
