Just remember what happened to the DHL A300 which was hit by a MANPAD system a couple of years ago:
The aircraft lost ALL hydraulic systems and ALL flying controls. It was landed with exceptional skill by use of differential thrust.
It is absolutely essential that all future large aircraft AND all present large aircraft are fitted with adequate defence systems and fuel tank explosive suppression systems.
The damage to the DHL aircraft's outer tank was caused by a fuel fire, not by the MANPAD system's warhead.
