Looks like a lot of wasted space. Higher fares to pay for the fuel... unless it has more than 1 level. Nobody actually has a window seat. Even those near the windows have their backs to them.
Leave it to the French! It was THEIR ancestors who invented sodomy, wasn’t it? And isn’t that the epidome of doing it incorrectly?
Like the tee shirt I saw on a biker chick on the back of a Harley, “If you think sex is a pain in the @$$, you’re doing it wrong!”
That reminds me of a story my 70 year old aunt told.
Someone at her work had brought in a chocolate dessert and said it was called “better than sex.” She replied, “You must not be doing it right.”
