There was someone that commented that if 2 lifting surfaces made
sense, you'd see the 777 with 2 wings because they're Boeing and have
lots of money and super human engineers. I've worked for lots of
companies like Boeing (but not them because they tried to low ball me)
and they're made up of regular guys like you and me. Many of them
have interests and responsibility outside of designing the best
aircraft ever, and really just want to pay their bills and go home and
have a beer. You work as one guy in a huge machine where decisions
are often made on what's politicaly the best answer rather than what's
technically best. You get one tiny componant of this huge project.
These kinds of organizations often punish risk taking in that there is
no upside pay-off if you're right. But if you're wrong, and it was
because you did something different than before, you get hammered. So
the larger the project, the more conservative the approach tends to
be. Remember, bean counters hate risk of any kind.

Bull****, Jay.

I worked for several years as an engineer in Boeing's Aero Staff.
Everything you just said is wrong. The people that design wings at Boeing
use the best technology available that's consistant with the production
materials that are available. They don't design on the basis of some
political whim. They don't design biplanes because it's easy to show
mathematically that the mutual interference between the circulation of the
two wings decreases the efficiency of both wings.

You seem to have strange theory that just because something isn't done it
must be a good thing to try. Subsonic aerodynamics was well explored by
World War II. Much of transonic and supersonic flow was understood shortly
after. If you think that you've come up with something new that just means
you don't understand why thinks work. If you want do to something different
just to be different go ahead, but it will be an inferior product and
possibly dangerous. Your current design has at least three fatal flaws.
You need to open some books and understand the theory of flight before you
start designing airplanes.
