Damn! That site's not available at the moment! "...exceeded its allocated data transfer...".

I'm a little bit tempted by the Fokker Eindekker - one of the few monplanes in the war, & a frighteningly effective fighter in its day. I have to go for something Sopwith though (call it English bias if you like!).

I could go for the Sopwith 1-&-a-half strutter, if only for the name (why build it with 1 1/2 struts?!), the Snipe was probably the best fighter of the war, though it only just made it into service before the end. The Triplane was a damn fine aircraft too.

But, perhaps inevitably, I have to plump for the Sopwith Camel. A superb warplane, tricky to fly, but highly manoeuvrable, & one of the first in a fine British tradition of giving our planes a bit of character by giving them names, instead of boring old Mark/Type numbers!! :)
