Avoid Missiles:
Elude missles quicker by doing barrel rolls and flipping in the air. About 80% of the time you'll be able to get away from them.

Unlock Extra Missiles:
This is a sneaky little trick to increase the amount of single shot homing missles on your aircraft from the allowed three. What you have to do is pause the game and remain idle for about 15-20 seconds and then resume the game and an extra three missles will have been added to your arsenal. You can repeat this trick until you have a total of nine.
