This was the largest land-based plane in the world in the 1930's and here is footage of it via Youtube: YouTube - Junkers G38 Airliner Another interesting aircraft design of the 30's. I am starting to have my aircraft interest rekindled by designs such as this! Here's another site with piccies: Junkers G 38
That made me look at large planes in general, I had no idea the Spruce Goose was still with us (Not that I know much about the aviation world!). Never heard of this big beast either: YouTube - Mars Flying Boats Though I have seen that massive Antonov take off, and frankly it just shouldn't be able to :mellow: : YouTube - THE WORLDS BIGGEST PLANES!!
Here's another page showing some more pictures of the G38 and some technical info too. Great picture of it near a Zeppelin! EADS N.V. - Junkers G 38
