Many anti-aircraft missiles self-destruct (by triggering the warhead) if they lose their target or run out of range. I believe this is a standard feature for most modern implementations. This minimizes the possibility of collateral damage, especially if you are using it over your own soil. Even some air-dropped munitions you might not expect, like the bomblets from cluster bombs, will self-destruct before they hit the ground if their sensors don't detect a target within their damage radius. Modern weapons go to considerable lengths to proactively auto-disable/self-destruct after deployment.
