BEACHHEAD:

Always go through the Hidden Passage to get your points up and then you only need to 
shoot ten planes. 

When you come to blowing up the ships, the aircraft carrier is about 40.0 degrees and 
the little boat on the right hand side near the edge of the screen is about 20.0 
degrees. If it says 39.0 degrees and under it says 100 too short, it will be 39.5 
degrees, because 100 is 0.5 degrees.
