To keep your pilots alive forever make a copy of the
ROSTER.FIL file before going on a dangerous mission. If
get killed you can copy the file back and your pilot is
resurrected as though he had never flown the fatal mission.
For example to copy the file type change to the Gunship
directory and type:
COPY ROSTER.FIL BACKUP.XXX
To resurrect a pilot change to the Gunship directory
COPY BACKUP.XXX ROSTER.FIL
Make sure you copy the ROSTER.FIL file every time you
successfully complete a mission.
