Hi,
I oppened the first mission after tried it unsuscesfully to look out what happens, and I think the problem is the area to check the mission goals, cause you have to exit the mission when the conditions are true -> part of group IN zone, and ussually you land and go to parking area... leaving the area.
If you want baltic_dragon, you can mark he player has landed marking it with a flag
player speed < XX (to avoid player or wingman overfly zone)
and
part of group in zone - land
then
FLAG XX -> ON
and later check if FLAG XX is ON to pass the mission.
There are others ways, but this is similar to the edited one.
PD: sorry my bad english
