Star wars

It's well known that there are many errors and strange things going on
in Star Wars, but I've never seen anyone comment on one rather large
plot hole.

You'll all remember that Han, Luke et al board the Millenium Falcon at
Mos Eisley under a barrage of laser fire from the imperial storm
troopers. You'll also remember then that but a few scenes later the
Millenium Falcon is pulled in to the Death Star, whereupon it is
searched. Cue Storm Troopers finding nobody aboard and accepting that
as a possibility.

Quite apart from the fact they're suggesting a space ship can pilot
itself through hyperspace sans crew, surely their comrades back on Mos
Eisley would have phoned ahead and told them to expect a ship with
three people, 2 droids and a walking carpet on board? No? Maybe the
storm troopers were in the Cantina bar getting drunk.....
