My guess is that a Blended Wing Body is a superior trade off if you
have a huge fuselage - as is the case for a large cargo jet such as a
C-5 or a big passenger jet. This allows the huge fuselage to also
generate lift, it appears to have a lot more wetted area.

NZ's CT/4 Airtrainer is a 2-seat piston powered basic trainer reputed to
get something like 20% of the lift from the cockpit canopy. It's in
service in NZ and Australia and also Hong Kong and Thailand.

Those who were at the '95 Worlds in Omarama may recall an aerobatic
display by an RNZAF team in CT/4s.
