BLU-109 Bunker Busting Bomb // Notice the pulverized concrete ejected out the entrance point (only possible with high explosives). Notice the delayed fuse and detonation occurring after penetration of the structure. Warhead of the BLU-109 is made of Depleted Uranium and leaves high levels of cancer causing radiation.
No set up required. Notice the pulverized concrete ejected out the entrance point (only possible with high explosives). Notice the delayed fuse and detonation occurring after penetration of the structure. Remember the high levels of radiation found at GZ and the subsequent number of cancers in the following years.
That would possibly explain the 'nose' coming out the other side of the building when it exploded.
True, Depleted Uranium turns into a ball of plasma after impact and detonation.
However, that footage could also be the engine that exited the building. Hard to tell because of the chop edit.
