well i didnt like the flight model on the psp version no barrel rolls etc you basicly turn left and right up n down picture this
turn left towards an plane then let go of the nub and it will level out and head straight for the plane its like your on rails i mean you cant even loop on it ?? also i found it to be quite buggy on one of the missions i think its the second or third mission on the battle of britian you have to kill a sub now this sub was flying !! yes flying across the water at speeds akin to a missile sorry but no uboat ever invented could pull that off
