The 737 has a root airfoil, two midspans, and one outboard. Is the midspan located under the fuselage or between root and tip?

1$\begingroup$ You don't need an airfoil under the fuselage. "midspan" is between the root and the tip as the name suggests. $\endgroup$ – DeepSpace Jul 25 '19 at 19:17

The midspan airfoil is between root and tip, so somewhere along the half span of the wing. Midspan is therefore a misnomer, but sounds better than midhalfspan.
