Doubting the Dianoga.

1. Ignoring the question of how Princess Leia could possibly know where the trash compactor is, or that the vent she blasts open leads to a good hiding place for the rescue crew, why are there vents leading down there at all? Would not vents leading into any garbage-disposal system allow the fetid smell of rotting garbage, spores, molds, etc., to seep up into the rest of the Death Star?” Resolved: The Death Star’s trash compactor makes no sense.
