You mean this? Or maybe this.I can confirm that the saucer does split across the void having studied the crash scene and watching a lot of behind the scenes for that ...scene...I could have sworn I saw the saucer itself fracture, laterally bisecting the void. Need to watch the crash again to verify. Stay tuned.
Go To YouTube and search for ILMVisualFX and there's one with the Vengeance crash as a thumbnail. some nice VFX shots !!
