Back in the 80s I used to fly hang-gliders and as the developement of these a/c progressed, the first type started to appear with no vertical surface at all. So you effectivley had a flying wing. All of a sudden pilots were complaining about dutch roll as the a/c was flown at speed. It became apparent that it was pilot induced and once this was known pilots learned a different technique and all was well.
I only add this as a note of interest but it does beg the question, how does a tail-less a/c such as the B2 damp out DR?
I can only assume it is by independent and computer controlled use of aileron, am I right?
Or do the pilots just lean over one way to weight shift it back to normal?
