Cute joke (attached) and interesting that they reference gliders.

I wonder if what the chicken with the yellow hair thinks happens to cruise speed is correct for an airplane (versus a glider). That is, at a certain throttle setting in an AIRPLANE does increasing the wing loading magically also increase the cruise speed?
In a glider increasing the wing loading (and gross weight) with water ballast shifts the performance curve (aka polar) so that the aircraft’s “best” cruise speed (called minimum sink) shifts upward. Meaning you can cruise faster between thermals and that’s important during a contest. But nothing is free as you pay for this gain by needing stronger lift as a lighter ship would need.
My $0.02.
