My Dad and I have been talking about, yeah, if the monorail were being pushed by the tow, and the bar failed, momentum would drive the tow into the cab. So then that let us to thoughts of, "did it break," or was a locking mechanism not properly secured, or some connection failed. So then it's thoughts about proper operation of the tow. The Columbia accident was a result of improper materials (the wrong line), improper maintenance (rot on the boat), and improper techniques during docking. It's good this occurred during testing, and so no guests were in danger, and no injuries. But tests have been going on for how long, and they aren't past accidentally running into things? So I'm not quite sure how the lack of even more major damage means this is a complete non-story. It's a different narrative now, obviously automation is not going well.
