It does make you wonder, and I often do, what the reaction of cabin crew would actually be in an instance like this. It will be interesting to find out, as we surely will eventually, what conversations actually took place.
I know for certain that if I was sure something was wrong then I would be up out of my seat, and, not get back in it again until something was done.
If the photos are correct the crew of the RYR must have surely have been able to see the damage to the AA. If they did and did nothing about it I find that incredible.
