The Flying Wing

Northrop B-2 Spirit
The Nazis were working on a flying wing during WW II.

Northrop N-1M from Wikipedia
In this country, during the war, Jack Northrop had one.  The Northrop N-1M, was yellow and had two pusher props.  It was considered successful.

YB-49 from Wikipedia

They went on to build the YB-49 which was, of course, jet powered and projected to be a bomber.  It tended to wallow as it flew keeping the pilot very busy dampening the un-commanded movements.  If I recall correctly, they built almost 100 B-49s before the program was call off.

The B-2 is also a flying wing.  It works because the un-commanded movements are dampened by the fly-by-wire computer.  Its stealthy qualities come from the inherent low radar cross section of the flying wing.  In addition, the aircraft is coated with a radar absorbent material.
