1. An aircraft with a lifting body fuselage profile, consisting of:
a vertical tail section and a nose;
a fuselage profile having a nose end and tail end and having an upper surface between said nose and said tail end and a lower surface between said nose and said tail end;
said profile of said upper surface having a section of a first ellipse starting at said nose end and a first circle arc transitioning from said first ellipse section to said tail end;
said profile of said lower surface having a second circle arc transitioning from said section of said first ellipse of said upper surface at said nose end and transitioning to a straight line, a third circle arc transitioning from said straight line and a fourth circle arc transitioning from said third circle arc and ending at said tail end; and
wherein said fuselage is 44.3 m in length from said nose end to said tail end, wherein said first ellipse uses a=15 m and b=8.2 m for equation of said first ellipse, wherein said first circle arc has a radius of r=64.2 m and subtends an angle of 27 degrees, wherein said second circle arc has a radius of r=2.25 m and subtends an angle of 90 degrees, wherein said straight line is 31.25 m, wherein said third circle arc has a radius of r=17.3 m and subtends an angle of 10 degrees, and wherein said fourth circle arc has a radius of r=18.35 m and subtends an angle of 30 degrees.
