icapacitated chopper problem

//incapacitated falling out of chopper again, when others enter it
//Problem is, that in life state incapacitated the unit is kicked out as soon as somebody else tries to enter.
//Idea 1: Fill space from highest to lowest. So they still get kicked, but only if the space is needed.
//Idea 2: Lock the cargospot they are in. But unlocking is a pain... Thx Bohemia!
//Testing Code:
0 spawn {{if!(_x == player) then {
_x setUnconscious true;
_x assignAsCargo H;
_x moveInCargo H;};} foreach units group player;};
