Still not sure if a Frame Shift Wake Scanner is helpful or not... they tend to jump to other systems, but by the time I get there they're nowhere around. Not sure if I'm just too slow, or if they "magically" reappear back in the original system. The last time it happened, by the time I got back, their hull/components/shield were at full strength again, and they had a wingmate in tow. And I wasn't gone that long, either.
