Abort bad mission:
You can't usually warm boot your machine with [Ctrl] + [Alt] + [Del]
keys while A-10 is running, because the game disables.
But, if you have a bad mission and don't want to save the results of
a mission, there is a short period while the next part of the program
is loading when you can use this key combination to do a warm boot.
After a bad mission but, while the next section is loading, hold down
[Ctrl] + [Alt] + [Del] keys. When you restart the game it will be as
if your bad mission never happened.
