I assume the bomb is GPS guided not laser targeted? The aircraft filming that must have know the exact coordinates of the drop as the bomb hit right where the cross hairs were on the camera.
Yes, the MOAB is GPS guided. As well, if you watch closely, the bomb lands to the right and outside of the crosshairs. I’m sure the plane watching knew the location of where the bomb was intended to hit.
Public information says it is GPS and guided by grid fins. There maybe other methods that are secret, but it is guided.
