In Ultimate, when is the disc considered possessed during flight?

• A. Immediately when the disc leaves the thrower's hand
• B. When the disc lands out of bounds
• C. Only after a turnover occurs
• D. When a player catches the disc and fully stops rotation

Answer: (D)

Possession in Ultimate is established the moment a player gains clear control of the disc. This control is shown when the disc is caught and the player can secure it, bringing it to a stop so it won’t slip or spin in their hands. Therefore, possession during flight is defined by catching the disc and fully stopping its rotation, which is why the correct choice is the one describing catching the disc and stabilizing it. Leaving the thrower’s hand just means the pass is in progress, not possession yet; the disc landing out of bounds or a turnover occurring later don’t define possession during flight.
