Very sobering reading. Many things went wrong, but the final problem was the inability of the potential rescuers on the scene to open the doors. I am sure it would come as a surprise to them that they don’t open like car doors and that it was necessary to find the latch on the top (actually the bottom as it was inverted) of the door which was 2 metres underwater in the mud and then rotate it, as well as pulling the latch towards the bottom (top) of the door. Seems possible that the passengers didn’t know that either.
