Was the Pterosaur designed by the Intelligent Designer or created by God?

They are one in the same. Unfortunately, many IDers don’t know it yet.

I saw an article about the Pterosaur when it first came out. And the way it was written, it appeared that the author did not know how most birds land, in a flare. Having dabbled in hang gliding, besides always checking that you are clipped in, the first instinct to overcome is the desire to plant your feet on landing(not a fun outcome). The first step in landing is to convert all vertical velocity to horizontal, then let the horizontal velocity bleed off mere feet above the ground, when you hear the air starting to stall over the wing, you push the bar full forward, often at a full run on the ground, converting the remaining horizontal momentum back into vertical, stalling the airfoil, and then you land on two feet, completing a flare. That a Pterosaur would know this is not surprising. The flare is something the birds all know how to do. What I would like to know, and this was not evident from the “prehistoric runway” article, was given the flare, do they have any idea how fast the pterosaurs were flying just before the flare? Minimum controllable airspeed would say something about the efficiency of the airfoil for a given wing geometry. It would also say something about the air density.
