What can I say?  I just like the flying wing. Also I should point out that the Illustrated London News is an excellent resource for schematic cut-aways like this–I think that I have 125 or so of them here for the 1910-1945 period.

Junkers built this fabulous flying (“inhabited”) “wing only”
aircraft, sending it up for commercial service in 1929 as the largest airplane
in the world. Only two were built (though a Japanese military knock-off ran to a production quantity of six), and I imagine that it was quite expensive making the Berlin-London flight, cruising in around at 109 mph.
