Take out enemy fighters Go to the outside view of the B-17 and put the mouse pointer on the far right. A box should appear with a few planes. The Americans are the planes next to the stars. The Germans are marked with + sign. Now click on the German planes and take control by pressing M. Then, bail out. Then use the [ and ] keys to get the whole squadron. Do this to each squadron to become fighter-free.
Get the P-51 To obtain the P-51 you have to start out in mid to late 1944. Note the missions are a lot harder.
Get the ME 262 Start a mission in mid to late 1944, then make your way to the heavily defended areas.
Custom soundtrack Replace the game disc with an audio CD while playing. The game only uses the CD-ROM for music. The music from the audio CD will play in the menus, but not in any missions.
