Because when you fly the SAAB you would never dream of having auto throttles. We would love to be able to navigate other than being a /A. It is fun having to fly with Low enroute charts out and actually using ground based navigation facilities, having to track a radial yourself.

Still, I love the SAAB.

Oh and to answer your previous post there is an aircraft that can take off on it's own, although it did not turn out too well.
