'No, as I understand it, an FAE explodes on or above ground. The shell is not really designed to penetrate. It basically explodes into a gas vapor cloud and then the gas vapor cloud is ignited by some ignition device after the cloud has had time to expand sufficiently. The burning fuel in the cloud demands oxygen and creates a vacuum for some radius around the burning cloud. So, it not only causes a horrendous fire, it also consumes all the oxygen in the near vicinity." Kind of like a fully-fueled commercial airliner impacting a tall building???
Those 'high-tech bullies' of the Al-Queda used the Volkswagon version of the FAE. "Drivers wanted"
