Here's the solution to those unexpected sim crashes, those interruptions by the wife or kids that caused you to mess up your normally impeccable landing(!) etc etc
It automatically saves your flight every 60 seconds and keeps the last 10 saves in your folder.
If your sim (or you!) crashes, it automatically restarts where it left off - usually only seconds before the 'event' happened. Or if you want, you can 'select a flight' and pick one of the saves - great if you want to practise ILS approaches for example..
It works for all versions inc FS98 - FS2004.
HIGHLY RECOMMENDED if you don't know about it already
