Luft'46 has been on my Aerospace Links list (see sidebar) for a while. I thought I'd featured this link in a previous post but so far haven't found the post. Wayne Hill just featured the site on his blog and I though I'd correct any potential omission here. The site is packed with real (and some possibly imagined) German planes, rockets and rocket-planes. Here are two that caught my eye (I haven't rescanned the whole site - there's a lot there!)
Josha Hildwine's A6 concept art:
Ronnie Olsthoorn's Focke-Wulf Triebflugel. OK, not a practical design for a real vehicle or even a flying model, but I'm fascinated with spinning thangs.
