Unlocking all planes

[BlazingAng]

I finished the game on the highest level of difficulty, all secondary missions accomplished, but in the last mission I can't unlock all the planes, although I have 11000 prestige points. Any idea?!

Beat all missions in Ace. I think thats how I got them. Play in the hardest difficulty and with an Ace rating.
