While detailed design of the projected New Midsize Airplane is still years away, Boeing has confirmed for the first time that the concept will be based around a composite fuselage.

Reveling the first outline design elements of the proposed aircraft to ShowNews at the Paris Air Show, Boeing is showing a 787-like twin-engine tube-and-wing concept with high-aspect-ratio, fifth-generation composite wings. However, the "tube" in this case is unusually shaped, being made up of a "hybrid" composite fuselage with a cross-section whose shape is between that of the circular 777 and that of the ovoid 737. More details are expected to be unveiled today.
