Jetzero is finally gonna do it

This design has been around for many many years but now it looks like the real thing will finally get off the ground supposedly by 2027.

Yes the concept has been around for decades.  

First, the good news.  There's no doubt that a design like this, where there is no distinction between the wing and the body is more aerodynamically efficient. 

Now the bad news. If you put passengers in an aircraft like this, most of them would have to be seated off the centerline.  That means that if the plane rolls and/or yaws side to side (which it certainly will) those passengers will experience extreme g-forces up and down and side to side.  It would probably make most people sick and/or injure them.  That's one big reason airlines have been very reluctant to adopt this kind of design.  I don't know how this company plans to deal with that problem.

The other problem is that it is a totally integrated design.  Every part of the aircraft is sized and shaped to operate efficiently with every other part.  With a conventional wing-and-tube design (like the 777, for example) you can alter either the wing or the fuselage pretty easily.  So if you want a version that can carry more passengers, you stretch the fuselage a little bit. If more efficient engines come along, you just hang them off the wing in new pods in place of the older ones.  So one basic design can be easily and cheaply modified over the years to serve many different missions. With an integrated wing body design like this you can't really do that.  If an airline decides it wants a version that can carry 50 more passengers, you would have to change every part of the aircraft.  It would be a completely new design, and a lot more expensive.  

It seems to me that the best use case for blended wing body aircraft is probably as cargo and/or tanker applications.

Maybe a new syndrome?  The Stockton Rush / Titian sub syndrome.  Owner more concerned with ego and making a profit off of ”adventure” travel than actual safety of design?

Or maybe the passengers will sit is a compartment that stays in place as the jet rolls around it?
