I read in the paper about a flight being delayed once because the Jewish male passengers wouldn't sit next to women so everyone had to shuffle about.
That was on an ELAL plane. It was ruled discriminatory and illegal. It was nothing to do with true Judaism, but the result of 'men shouldn't touch unrelated women' evolving into 'women should be moved so as not to disturb men' - ie the misogyny that evolved. The cabin crew, as many people do, found it easier to bully the quieter 'weaker' person, than to stand up to the bully (United Airlines?)
the wires in areas of North London to extend the home, so you can still push a buggy round the streets, etc.
The rules for observing the day of rest on the Sabbath forbid various forms of work, including carrying or pushing things in public places. In those days, communities were much smaller, and separate households less distinct from each other, so you could consider that you didn't pass through truly public spaces on your way from home to synagogue. Particularly if you lived in a walled town. The wire is a symbolic wall, defining a communal area, allowing strictly observant Jews to, say, push a buggy within that zone on the Sabbath.
Also that photo of a Jewish man on a plane in a clear, giant plastic bag. Think that was to do with not being allowed to fly over graveyards.....but if you're in a plastic bag it doesn't count!
No idea what you are talking about. Sounds like complete nonsense to me, but then some of the ways the ultra-Orthodox come up with to cope with the realities of modern times sound complete nonsense to me. (See above!)
