The script destroy()ing the planes after an amount of time (in the example 60sec). So by creation of the plane you give a "selfdestruct" command that are executed the time you specified. To avoid vanishing of other planes you should specify the planes. In example only the Stukas, Ju88, He111H2 und P2 will be destroy()ed. Destroy() means the plane is removed from game.

An other possibility is to check if the plane reach the last waypoint and then destroy it, but this is a little bit more complicated.
