You can't usually 'soft' boot your machine with [Ctrl] [Alt] [Del] while
A-10 is running. 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 'soft' boot. After a bad mission
but, while the next section is loading, hold down [Ctrl] [Alt] [Del]. When
you restart the game it will be as if your awful mission never happened.
