A letter in The Register:

        http://www.theregister.co.uk/2005/08/23/letters_2308/

points out:

Flying wing designs have many attractions but there are two major
problems concerning their application to passenger aircraft.

        1) Evacuation: it is not possible to incorporate sufficient
        emergency exits to evacuate all the passengers in the requisite
        time.
        2) Roll rates: people seated furthest from the longitudinal axis
        of the plane will be subject to unacceptable acceleration when
        the plane banks in a turn.

It would make a nice freighter if any aircraft company was brave enough
to finance development of a pure cargo aircraft. That's not a daft idea,
an ultra quiet freighter that could use airports overnight would be a
very good thing. Sadly, I can't see it happening.
