# Flight of a Glider

Flight of a Glider

$Aborted

This Demonstration shows the flight path of a glider, depending on the initial velocity of the plane, its release angle, and the plane's drag coefficient . The flight is governed by Lanchester's system of autonomous nonlinear differential equations:

v'=-sinθ-d
