Hello, it is very strange that this crack progresses on both sides. I have no idea how. If the impact had occurred, I think that a crack would have formed from the direction of the impact to the other side. Does anyone know how this crack is formed? There was no fall.

Nötr: During  flight I go straight like an arrow. but the progression of the crack scares me.
