I've also had an articulated bus (here in SF Muni-speak they are called "Artics" and the drivers have an igloo patch on their uniform, they don't seem concerned about spelling) do a similar number on a Coleman lantern I had picked up at a garage sale. These are quite dangerous and though they have the "pinch points" pretty well covered against hand and foot loss, the places where you put parcels (and on a crowded bus this is crucial) are traps! My mint-condition Coleman was a total loss in seconds, not a thing I could do but watch it crushed...I learned the hard way.
