That's your mistake. The trick in the trick question is that it is phrased in a way that encourages you to interpret its spirit rather than its words. It subtly encourages you to choose the physically impossible interpretation.
If there are two interpretations, and one requires a treadmill that can stop a jet engine using friction in the bearings of the landing gear, pick the other interpretation.
