During the initial years of the Galactic Empire's reign, the Coruscant Security Force mistakenly flagged Darth Vader's starship as belonging to a Separatist remnant group. Because Vader's ship experienced communication jamming, preventing it from sending the correct access codes to Coruscant's defense systems in orbit, a missile platform fired a volley of missiles, which caused Vader's vessel to crash land on Coruscant. This event was actually a component of a larger conspiracy orchestrated by certain Imperial officers seeking to eliminate Vader.
