Unable to choose a plane in Co-Op missions

[EAF331 Starfire]

This might not be a good answer so bear with me.
It seems that only the host can choose an aircraft. You do that by slecting your aircraft on the map screen. After that you will have to have all your copilots on Teamspeak/Ventrillion. When they are ready and the mission is loaded you should press the Begin Battle/Start Server button. After that everyone will have to play "catch the horse".

In essense. The COOP part are almost useless.
We need a list like the one in IL-2 1946.
