The plane you set in the flagship is locked. The quest upgrades the plane it asks you, so make sure to get it unlocked. Just retire the plane and before equip it again remove the lock, then try again. I've been told it's not neccessary to scrap the plane quests again, so go ahead a recover your prize.
