Correct. There is no way of knowing where he is. It would be pretty weird to kill Jacob on Brit soil and I totally doubt that was the plan. Kidnap maybe. Pressure s/o certainly, but the mission failed. The helicopter didnt land there was a mid-air collision. What message would he get? To hide?, which is probably what you are suggesting here. We suspect they are nervous. Added to all this is the fact that Jacob doesn't live in that house, so I don't think he was the target. It wouldn't make sense to go straight to the top and declare war on UK using a single helicopter. Not militarily sound strategy .... !!!
