Footage of how the GBU-57 bomb works.

@TheJointStaff: Unlike a normal surface bomb, you won't see an impact crater because they're designed to deeply bury and then function.... All six weapons at each vent at Fordow went exactly where they were intended to go. A bomb has three effects that causes damage. Blast, fragmentation, and overpressure. In this case, the primary kill mechanism in the mission space was a mix of overpressure and blast ripping through the open tunnels and destroying critical hardware.
