Agree. Each day,decreased number of old cool planes, which flight from 1940s and still in flight condition. I cry every time see, how good maintained old aviation history in US, comparable to exUSSR. Even more impressive, there are examples of old soviet planes in flight condition in US - you will not see them flight in exUSSR. Unfortunately, not all 1940s engines have modern substitutions. For me this is our history. I think it is acceptable to make for them exclusion from rules.
