One of the things I always hated about the Star Wars Books/comics is that they made the Bounty Hunters seem like a mix of SWAT-trained, Special-Forces hardened, know-it-all, tech-geniuses rebellious superheroes and that bothered me.....being Boba Fett the main representation of that approach. Boba was an orphan clone who had to learn the ropes on his own, if he was clever to piece the trajectory of the MF better than the imperial officers who had the might of the Empire behind them, that was just (I think) a once in a lifetime break, since in ROTJ he fails miserably to stop a half trained Jedi like Luke. It really is hard to imagine how the Imperials with all their computers couldn't just plot a trajectory or have a sensor to detect the MF there, but still.....Boba was by no means infallible.
