Not to drag this too far afield, but a friend of mine set up a small organization to encourage the building and flying of WW1 replicas: www.greatwaraerodrome.com

He just finished (and has flown) a replica Sopwith Tabloid. The advantage of the tabloid is that it is a side by side aircraft, which he intends to use for orientation and training -- hopefully encouraging people to build and then preparing them to fly their own airplanes. Looking at the aerodrome forum I see that snj5 has already seen pictures.

It is a replica, rather than a reproduction, using steel tubing (and very strong) and a Cub airfoil (very safe)

He wanted to bring it to OSH this year (and park at RFA) but he had to start Army War College that week. Hopefully next year.
