An aircraft defining a longitudinal direction and a vertical direction, the aircraft comprising:

• a boundary layer ingestion fan defining a centerline and comprising a plurality of fan blades rotatable about the centerline;
• and
• a fuselage extending between a forward end and an aft end along the longitudinal direction, the boundary layer ingestion fan positioned within the fuselage at the aft end of the fuselage, the fuselage defining an inlet upstream of the boundary layer ingestion fan, an exhaust downstream of the boundary layer ingestion fan, and a bottom side along the vertical direction, wherein a portion of the bottom side of the fuselage forward of the inlet defines a forward reference line, wherein a portion of the bottom side of the fuselage aft of the inlet defines an aft reference line, and wherein the aft reference line is substantially aligned with the forward reference line.
