A Physicist demonstrates on German television how a full body scanner is unable to find thermite hidden on his body. The end of the video shows how this easily made substance burns though a frying pan. The thin aluminum skin of an airliner would be no match, as the temperature of the reaction reaches up to 4500F. While the video is in German, it is easy to understand, and the scanner operator speaks English. You can hear him stating that the device can not find objects hidden inside the mouth.
