How is not major? It’d be like if the original Star Wars never explained what the Death Star weakness was.
Not at all. It’d be like if the original Star Wars never explained why Leia couldn’t just beam the plans directly to Yavin.
Easy, too big of a file for that distance, and possibly it couldve been traced to the receiving point and the rebel base location revealed. Granted, they had transmissions between Yavin and the Rogue guys, but those were quick verbal transmissions, not large files of information that maybe wouldve been easier to trace. Who knows? In the real world, during my ARMY commo days, transmissions were made to be short and to the point to avoid be located in some instances. Maybe the same applies to transmitting the plans to Yavin.
