the janek thing

My thoughts on the whole Janek in a space suit with shaw theory is this: Captain Janek does indeed give the orders to crash the ship into the derelict, but does he perform the action? No. I believe david or one of the co-pilots does the deed, allowing Shaw and janek to get away and find vickers who has already left. They eventually end up searching the crashed derelict or the temple, but find that whatever was on the ship survived etc. Thats my theory at least. If not this, i do believe 3 people will survive the crash due to the fact there is 3 escape pods :) Any thoughts?
