There's so much I don't know about airplane design, but don't recall
ever seeing structure so close to the exhaust plume of a jet engine

gravity would have been a design goal, but they know more about design
than I ever will. Never the less, what a beautiful airplane that is.
Do they take American Express?

IIRC, some of the very early jets--especially German--were built exactly
this way.

It should have an added advantage in being unlikely to injest foreign matter
from the ground or thrown by the tires; but early rotation has been an issue
on various jets in the past.

In any case, it is very, very cool!


The thrust line looks off to me for good low speed handling during
power changes. My concern would be handling and COG issues for T/O/L .
Fuse may look slippery but that nacelle looks too unfaired. The D-jet
looks like better aeronautical design to my eye -the engine has been
included in the aerodynamics rather than being an add on power pod. I
wait with interest the first flight tests...
