how to trigger the big yellow messages?

[David198502]

btw, we as a squad tested the script another time, and while the spawnplaces are all working, when you come back to any of your friendly bases, the winning message didnt show up for some reason....

i dont know why, cause when i tested it alone, with only a few aircraft on both side(for testing puroposes), the message came up, as soon as i smashed all planes into the ground.
maybe it has something to do, that many of us, did crash landings in fields, or ditched in the water??
i dont know, but the message just didnt show up...
