sentences:  Hence, Jones's theory makes it applicable to more complex shapes like entire supersonic aircraft.A superficially related concept is the Whitcomb area rule, which states that wave drag due to volume in transonic flow depends primarily on the distribution of total cross-sectional area, and for low wave drag this distribution must be smooth.A common misconception is that the Sears–Haack body has the ideal area distribution according to the area rule, but this is not correct.
