Special drops are completely random and only available for a limited time.

Right now the special drop is Pixy's F-15. You may get it on your 5th game or your 100th game. It's truly random.

As for modifications/aircraft parts, you unlock them as you move along the aircraft tree. Focus ahead on what planes/parts you want so you don't waste time and credits on a branch you don't have an interest in.
