Elite Dangerous - Distress Call! Federation Fleet Destroyed By Thargoids

I got news about a federation fleet, that was destroyed by thargoids. I take my Federal Assault Ship out to investigate. When i arrive, i find one Thargoid flying around scanning the debris, picking up a escapepod as it goes around. When it leaves it try to follow into its wake, but gets pushed away violently. I fly back to inspect the damage done to the fleet.
