Form Follows Function

I would like to share a thought I had, and I was curious if others have already come to this conclusion or what other people think of this.

Wikipedia says :
Form follows function is a principle associated with modern architecture and industrial design in the 20th Century, which states that the shape of a building or object should be predicated by or based upon its intended function or purpose.

Looking at the shape of a UFO, it is not only aerodynamic, but its shape allows it to rotate in flight, without changing the way air flows around it. Any vehicle we have now, flying at very high speeds, faces the possibility of thermal damage from the extreme heat created from friction with our atmosphere. I suspect the UFO turning while moving would allow the heated leading edge to then cool down as the leading edge becomes the trailing edge. Continuous rotation would keep the crafts surface much cooler.

This would be a fine example of form follows function. Then again, maybe their form of propulsion is such that they have no heat to worry about at all.

I would like to know what everyone else thinks, though.
