Carpet of flying

Carpet of Flying: This rug is able to fly through the air as if affected by an overland flight spell of unlimited duration. The size, carrying capacity, and speed of the different carpets of flying are shown on the table below. Beautifully and intricately made, each carpet has its own command word to activate it—if the device is within voice range, the command word activates it, whether the speaker is on the rug or not. The carpet is then controlled by spoken directions.
