Sadly a fatal accident on Fri the 23rd near Denver with loss of "retired British wing commander", Brian North. He was flying a 2/3 scale repica of a WW I RAF SE5A biplane fighter, the he had assembled from parts in England. He took off at Front Range airport , just south of Den Int, and may have had engine failure, I am not sure of any details. The paper says he was from Parker which is just south of Denver, near Centennial airport. Weather was not a factor it seems.
