Is this what Zeb and Ezra did with the TIE they stole at the end of “Fighter Flight?” This image from the Star Wars Rebels Facebook Page seems to indicate that possibility:
Lothal’s vast prairies are broken by large rock formations and mountain ranges, the source of the planet’s rich mineral wealth.
That certainly would explain why Zeb and Ezra are laughing like they just did something really funny when they get back to the Ghost to find Sabine’s art project.
Hopefully the Empire doesn’t have LoJack.
Thanks to IG-88 MPH for the heads up.
