[0:00]As the bullet hit the tank, fuel would leak out, soaking into layers of rubber built into the tank walls. And one of those layers would begin to swell, expanding inward toward the bullet hole. As it grows, it squeezes until the hole shut, preventing the fuel from leaking out. You see the tanks used to be metal, and when they were shot, fuel sprayed into the air, turning into a mist that ignited the plane. So engineers used rubber instead, so it seals the hole and the fuel stays inside.
