    Stall Speed = 32 mph
    Air Density = 0.00238 slugs/ft^3
-   QBar = 0.11139 (slug ∕ (ft^2 * s))
+   QBar = 2.62871(slug ∕ (ft•s^2))
 We get
-lb = 0.11139 (slug ∕ (ft^2 * s)) * 280 ft^2 *Cl
+lb = 2.62871 (slug ∕ (ft * s^2)) * 280 ft^2 *Cl
-   Cl = 2688 lb / (0.11139 (slug ∕ (ft^2 * s)) * 280 ft^2) = 2.68 seconds, which is the wrong answer. :(
+   Cl = 2688 lbf / (2.62871 (slug ∕ (ft * s^2)) * 280 ft^2) = 3.65
