LM - with no disrespect meant at all, who came up with these guidelines? When this latest thread started in 2008 there were many references to other sources than the web (in fact the early posts were from books). The fact that challenges are posted puts them on the web. If we stick to what is available now then how is our ever increasing knowledge of past aircraft realised? I think this a fantastic thread and your contribution to it is enormous but I don't think we should be limited solely to what exists on the web today. That W33, that you identified correctly, is great example of this. You clearly got it because, after a bit research, you matched the wings. For me this is what the whole challenge is about and well done. Yes it's a kind of competition but surely we need to learn too?
