I can't comment on this particular incident. However, my own experience of flying with groups of adult ultra-orthodox is of unbelievable rudeness and lack of consideration for cabin crew and fellow passengers. Typically they gather in groups to pray or just chat with no regard for anyone else's comfort or for the obstacles they are creating for staff trying to serve the remainder of the passengers. I have flown around the world with groups from every possible nationality and religion but, as a general rule, these ultra-orthodox men are without doubt the most unpleasant and inconsiderate.
