I have to wonder how Darth Vader felt upon reading the field reports from the stormtroopers on Tatooine in Star Wars Episode IV: A New Hope. Days 5 and 6 must have throw him for a loop.
Day 1: Located droid parts near an escape pod, and two sets of tracks leading away from the pod. The tracks appear to be from an astromech droid and a bipedal droid. Based on the gait, the bipedal droid is likely a protocol droid.
