There appears to be one axial half-wave in the general buckling pattern of this long shell. Compare with the image in the previous slide, in which there appears to be two axial half-waves in the general buckling pattern. Probably this shell has sturdier stringers than that shown in the previous slide.
Some very local buckling of the external stringers is visible at the midlength of the long cylindrical shell.
