First comes why it came out (something missed in strapping down, hole in dummy, or wrong dummy); then will come how it came out.
If they find nothing in the why it came out (properly strapped down, no hole, right dummy); then the how investigation will almost have to happen. I bet it's something in the why it came out because these trains have been proven to be safe.
