Always keep an eye on the burners. Its very easy for the fire to take you wing or tail off, you hit the ground, but some how live. Iv seen many planes do this or just belly it in and get a ditch. Just because they are on fire doesn't mean you are getting a kill. Throttle back and watch if you are low on fuel. If you see them trying to land and still want the kill then WEP in and blast em.
