HM goes to his desk and takes another stack of parchments and begins to hand them out.

"If you would all look at this drawing of wing placement..."

Parchment

"The wings are connected near the shoulder. This is the most improbable type of wing. The surface is small near the body making the flight and even the glidding difficult, moreover the rear of the dragon tends to "fall" toward the ground.
However, this disposition gives good results if the dragon is hovering. Now tap the parchment with you wand to see the next image."

Parchment

"The wings are connected below the chest. The wings as shown in this image are somewhat between the shoulder blade and the theigh. Not a bad position, yet still not effective for maximum flight maneuvrability. And now if you all would be so kind as to tap your parchment one last time..."

Parchment

"The wings are connected near the thighs. This give a greater surface for the wings. The long neck and the tail give balance and enable the dragons to quickly gain or lose altitude."
