I flew just one single mission,i flew stukas, but i couldnt switch to my gunner, i tried everything,still possibility that it was switched off in realism settings,if there is such a option.other things i noticed, no collisition model for a radar towers

i could fly through them like a ghoust.comm with others planes still doesnt work, i can try to give them any orders and they still fly behind me like a morons.Also 1st german mission in a campaign is broken,everybody i flying to the meeting point but the bomber which we are suppose to escort is way ahead and shot down,once i tried to fly strait to the bomber not bother with the waypoints buti was late anyway,then i chased the spits?they just flew like a sheeps, didnt even bothered to fight,my wingman was deaf again,no response to a orders.please make proper campaigns with connections between missions,or add managment of planes and pilots like in red baron.thanks
