A rare Hamilton Metalplane is expected to fetch up to $1 million at auction. The 80 year old aluminum bodied craft is the only flyable version left in the world.

For 20 years during the pioneering age of Canadian aviation, an aluminum-bodied bush plane soared over northern forests and remote lakes as part of a government mission to map and monitor the country’s uncharted backwoods. Now, 80 years after Canadian forestry officials purchased the U.S.-made Hamilton Metalplane from a Boeing plant in Wisconsin, the meticulously refurbished and flyable aircraft — the only one of its kind in the world — is expected to sell for at least $1-million later this month at a major Arizona auction of vintage cars and planes. – from National Post
