>"Runways generally point in the wind direction, as aircraft take off and land more easily upwind. The designation of these is based on their respective alignment angles."
NO!!
This is exactly 180º wrong -- what generates lift on a wing is _relative_ airflow and thus pilots preferentially prefer to take off or land into a headwind -- which mimics speed "for free".
Likewise, tailwind landings are downright dangerous for the same reason, and each aircraft has strict (and low) limits for the maximum permitted tailwind. The illustration is exactly the other way around.
