That brings me up a new question. How did Kappa 3 survive so long in the Nebula? Did he eat his wingmen's corpses to survive for that long or what? Kinda sad though, I wonder what he saw. Hell, how was he killed? We just got this transmission from him and then poof, no more word of him.
My theory would be... the Kappa 3 you encountered was actually a ghost of Kappa 3. The actual Kappa 3 died on the Nebula patrol and was trying to send that transmission out. So somehow, the transmissions finally found its way to someone. Freaky ghost messages....
Another theory is... Kappa wing was actually a SoC wing that were going to investigate the nebula. I don't get why SoC make all this fuzz when they can just do the patrol covertly. So I'm sticking to the "Ghost Transmission" Theory.
