Beat all twenty missions in "Easy" difficulty setting and wait for credits to end. Then save the game. Go to options and there should be an option that says "Special". When highlighted, you can turn it off or on.

To get the EE Lightning plane, contrary to what Sega.com has to say, just shoot it down using only guns in the third mission to recieve it. It doesn't matter what difficulty it's on, either.
Also, to get the S-37 Berkut, shoot it down with guns on the mission it appears.
