Not noticing it, soon the KZA1907's tail cut through SVA763's left wing. The Boieng of SVA763 lost control and went into a descending spiral and hit the ground at 1135 kmph. The Ilyushin remained structurally intact as it went in a steady but rapid and uncontrolled descent until it crashed in a field.In the end, all 312 people on board SVA763 and all 37 people on KZA1907 were killed.
