Agreed, those pilots/survivors (mind you, im not talking about lifeboats with survivors from your latest merchant victim
) moving with current and wind is more realistic, but it is now prohibiting in completing objectives.
In real life, when a pilot manages to get ashore, he would stay on the beach and possibly swim TOWARDS the friendly sub there to help, right?
(remember USS Cod and the Dutch O-19 ).
So, i think for gameplay sake, floating pilots should be nailed to the spot.
