I don't think it's Fett either.I was trying to be silly. The Mandalorian is not Boba Fett. His backstory as a "foundling", rather than as a clone, has already been established in the first couple of episodes.
However, in episode 3 the Mandalorian gets kinda jealous of another character who does have a jetpack, and says, "I've got to get one of those!"
Also, the Mandalorian's ship, the Razor Crest, is waaaay cooler than Slave-1. Yeah, I'm going there.
Live action jetpack was cool. They did that in Rebels so watch that if you have Disney+ imho.
