I copied the text below form a post in the Diamond Aviators Forums by a fellow who lives in Switzerland and is based at LSGL (Lausanne Blecheret Airport, Suisse).
 
"The experimental world is fascinating, and I would have taken the plunge long ago. Now listen to this sad news:

Lucky americans.."

I had no idea that the rules in Europe on experimentals is so onerous. So I assume there aren’t many Lancairs based in Europe.
