This article is full of misinformation which is not surprising for Unscientific Un-American.

No one is going to shut engines off while landing.

Throttling engines back and "gliding" to "be greener" isn't going to happen either since the amount of throttle needed is dependent on the altitude of the runway and thus the altitude of the plane that's landing. The higher the altitude, the more power needed just to maintain lift and control.

False.
