Agree 100%, especially on PowerPoint. I had not seen that Wikipedia page (it's brilliant) before. It should be stuck on the back of the toilet door in every board room.

The image in the report is 801x1007 pixels, so most likely they have something much clearer. Even with the limited detail in the report, I feel if the cable tie (assuming that is what it is) was in...

The door plug only needs to lift half an inch or so for the 12 stops to disengage. The damage to the upper guides appears consistent with that to me. That there was (effectively) no bolt in any of...

Post 726 shows the live door and the holes in the upper guides are visible. I guess this reduces the spares holding required.
