The 367-80, C-135 and 707 have a "double bubble" fuselage cross-section.
On the 367-80, the upper lobe is 132" wide and the entire fuselage is 164"
tall. On the C-135, the upper lobe is 144" wide and the fuselage is 166"
tall. On the 707, the upper lobe is 148" wide and the fuselage is 170.5"
tall.

As near as I can figure out, the wings of the original 367-80, C-135,
707-120 and 707-138 are identical. The 707-320 has a much different wing.
By the end of its life, 367-80 had(has) a wing much like a 707-320.

Ah, so all three are different in FCS. thnks
