Passenger Jets fly really fast, but some Flat Earth people say they don't, that we're being lied to. In this video, I show you how to calculate the speed of an airplane from a video.

Speed is just distance divided by time, and there are two techniques for finding that speed, depending on whether the camera is on the plane or on the ground. Leave comments below if you have any questions or suggested improvements. However, please be civil - I know that discussions like this can end up in a shouting match, and I may remove comment with excessive name-calling and bad language.
