Wow. It's actually a miracle that this works most of the time. That suitcase is pretty standard, I could imagine a million ways how some backpack or other unusually formed piece of baggage would jam that thing. And how on earth do they route individual packages through the system with that speed? Is there some pattern recognition system that identifies them on the fly and then routes left, right, left right, etc? This reminds me of a funny part of a book I read about automation (and its impact on human labour), which described how modern corn mills identify bad grain: they shoot every single grain through a high speed tunnel and identify malformed (bad, moldy) grain with pattern recognition and then filter them out.
