| Again: In knife-edge flight, the weight is being supported mainly
| by the lift of the *fueslage*.
| a) You can get lift from things that don't look airfoil-shaped.
| Even a barn door will develop a goodly amount of lift.
| -- The lift-to-drag ratio might not be very good.
| -- The maximum coefficient of lift might not be very good,
| but this just means the stall speed will be high.

I am reminded of video footage of barn doors flying near tornadoes.
