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.
