The Sonic Cruiser design was about the size of the 767 with seating for
approximately 250 passengers. The airframe featured an aft-mounted double-delta wing with very large,
thick root extensions to provide significant fuel volume. Canard surfaces mounted near the nose would
provide pitch control. This arrangement had the advantage of providing a large, constant diameter fuselage
in between the canards and wing to maximize the size of the passenger compartment and provide space for
fuselage inserts in future stretch models. Engine pods installed along the wing trailing edge were
partially blended into the wings to reduce drag. Plans called for fitting engines derived from those used
on the 777.
