Notes:
1. M213 has an error in mission data. F117 is stuck in sand and unarmed.
2. Capitalization is important in these codes.
3. Enemy aircraft sometimes fly erratically, especially in the later missions.
4. You can "cheat" and receive mission awards by either flying the enemy transport/bomber and dropping your bombs or crashing before your mission is complete (M208 & M212- TU20 or M214-DC10) or flying one of the enemy fighters and destroying the target(s).
5. Pilot ejection seats do not work on B52s.
6. Additions and corrections to this list are welcome. Later files will be more detailed (numbers of each aircraft, initial position, arramement, etc.).
