Is it possible that the teal car had juuuuuuust barely passed that sensor before getting stuck, so the system thought all was well? I have no idea where the sensor would be located, or whether there might be two, one just before and one just after the critical point where the gondola rejoins the cable. To me, it would make sense to have two, so that if it passes one point, but not the other within x number of seconds, everything shuts down. But I have No idea how it’s set up.
Does anyone remember, with the MK Skyway, did they have any CM monitoring the cars as they came in and out of the station to make sure they didn’t collide or fail to launch?
