15Jyn runs Faster Than A Spaceship
At the beginning of the film, we see an Imperial ship fly over a young Jyn Erso. Jyn is running back home to warn her family of the Empire's arrival. Somehow, she makes it back to her home before the ship gets there. Not only does she have time to
warn her parents of the ship's arrival, but they also have time to pack.
It's definitely a cool shot, but it doesn't make any sense. Again, we see the ship fly over her head. It is clearly moving faster than her. Presumably, it knows the way to Galen's house. So how could Jyn possibly have gotten home first? Maybe the troops decided to stop for coffee. After all, it must have been a long trip, and even stormtroopers need to keep their energy up.
