Does anyone know what the comparative fuel burn was
between the "wing" and the B47?  (Pounds of fuel per
pounds of aircraft.)  One of the big selling points
for the BWB is that it is supposed to really beat the
747 in the area of fuel efficiency.  I've seen figures
as high as 25% in print.

First real point in favor that I have heard so far.
BTW reviewing most of the heavy accidents over the years very few
were a conventional semi controlled off airport crash landing. Some were
bombed or shot down. Most broke up in the air or flew into the side of a
mountain. No amount of crash ability will help the pax there.

    Denis,
    The immediate competitor for the Northrop wing was the B36,
with 6 (?) R4360 P&W "corncobs" buried in the wings with pusher
props.  Salina KS still has a 12,500' main runway thanks to the B36's
need to fly to Moscow from there on a hot summer day.  Amazing to
land on a 2.5 mile long runway in a C150 on your first solo cross
country!

    If the blended wing can deliver 25% fuel burn reduction, NOTHING
will stop it.
