We often talk in soaring about the glide ratio of a glider. That is, how far a glider can glide from a certain height (in calm air, with no lift/sink, perfect wings, etc, etc). For example, our Lark has a glide ratio of 34:1 meaning that at 1 mile AGL this ship could potentially travel 34 miles. Our 2-33 has a 22:1 ratio, the Krosno 27:1, the PW-5 32:1. Some of the private ships approach 50:1.
This interesting video https://youtu.be/jdwtNFbOmxM explores the glide ratio of other flying things. Unfortunately, the Frisbee was not one of them. 😉
