I'm not offended. It sounds like what the guy was trying to do was put the arc/cresent/whatever around the footprint left by the plane. However, I don't see how the stupid thing won because it's ugly and gives no context to what happened there. 100 years later, kids will come to this monument and see an arc and a hole in the ground and not have any idea what happened there.

And the arc points at Mecca? So the plane crashed facing Mecca too, didn't it? The symbolism of the coinidence is a little bit ... odd don't you think?
