Very interesting thread, and it prompts the question what is vintage, what is classic? any ideas? What are the “official” definitions?

Good question.

I know that for motorcycles (in Denmark at least) its more or less a question of insurance (the closest to an official definition). More than 25 years is classic, more than 50 years is vintage.

My own difinition of vintage aircraft, is anything before 1930. And for classic aircraft its between 1930 and 1960. But its not something I normally use for classification.

Surely a museum person must have a more solid difinition.
