Yes, accepted. I posted after another comment to that effect. My question/comment about damage on the ground still remains though again I saw your post about maintenance having been done on that door. If one was looking for a reason why it failed early on this flight and not on previous flights then one explanation could be that the cause was not present on previous flights.
