how to remove AI planes and AI vehicles?

[David198502]

hey guys....im just building a mission, where i try to load submissions randomly into one main mission.

what i dont know how to achieve though is, how i can "destroy" ai planes if they have landed, and also vehicles or trains, when they have reached a certain waypoint....

i have attached the complete mission...
there is one main mission, and 3 submissions which will be loaded randomly every 30seconds.
the problem with it is, that the trains and vehicles will just stay on the map.
i would like them to have destroyed when they reach their last waypoint....

in the script, there is a way to "destroy" planes after a certain time, but i would like to change it, that they will get destroyed after they have landed...
(i know that this will happen automatically, but only after 10 minutes)i want that the planes are destroyed after maybe 30seconds when they have landed.
