Do they teach kids nowadays even the basics of how an aircraft manages to stay up in the sky? I can't answer that question myself. Comparing the content of today's combined science GCSEs with my separate-subject O-Levels, I suspect the answer is no.
Anyway, I'll just carry on trying to be the best passenger I can be, and I do know that I can count on the ladies and gents at the front to be the best they can be as well. At least in the overwhelming majority of cases.
