Biplanes are some of the most stable, aerodynamically speaking. They are often used for air show stunts for just that reason. When you fly a plane straight up into the sky until gravity overcomes your engine’s tiny thrust, you want stability when you regain control on the downward portion of your trip.

I was a air-traffic controller in the Air Force, so I like this airplane ring! 😉
That sounds like an interesting job. I guess that means you can land a C5A.
