This argument is stupid and hilarious because they seem to have some kind of problem with the notion that yes, indeed, airplanes do pitch constantly down when flying even slightly longer distances. I don't even understand what the problem is, or why they think that's a problem.

They don't understand that's not how airplanes maintain altitude.
