Great comments and thank you very much John for your expertise! Looking at the flow pattern in photo #2, to me it really seems to corroborate exactly what you are saying. It looks like the fusion crust is flowing away from the nose.

To understand the overall flight orientation of this specimen and many others like it from this Fall, the top surface of photo #1 is the bottom of the stone in flight. The leading nose cone is on the left side of photo, and the tail is on the right. The top of photo #4 is the top of the stone in flight. Stable ride at thousands of feet per second at a flat 18 degrees +/- angle... this reality of a chunk of stone forming a shape by high speed flight is hard to relate to in human terms.

Nice stone. Seeing Photo #2, it appears this is another Chelyabinsk "projectile", bullet-shape, or in this case more like a small cannon shell. The back end ridge/rim and the surrounding reddish "low pressure" crust are the oriented-stable flight identifiers.
