Go to the System display. In the display tabs on the left side of the screen, one of the tabs is for
waypoints. Add a waypoint or two in the direction the missiles came from, then go into your fleet
order screen, check the box for waypoints so they show up as a valid destination, select the waypoint,
the "Move to" command, and there you go. You can make you fleet move on any direction using
waypoints. NPRs do this too.
