A wing generates a lift ${?}^{{?}^{?}}$ when moving through sea$-$level air with a velocity $U.$ How fast must the wing move through the air at an altitude of $14600$ m with the same lift coefficient if it is to generate the same lift? Use Properties of the U$.$S$.$ Standard Atmosphere $($SI Units$).$ Assume that the lift coefficient is a constant.

$\frac{U_{14600}}{U_{\text{s}\text{e}\text{a}\text{l}\text{e}\text{v}\text{e}\text{l}}}=$
