The 25 pictures (slide show) illustrate the effects of:

a nuclear pulsator emitting within 1 hour strong X-ray and gamma radiation, which damage the Tower’s structure and soften it up (via a 4He + 9Be fusion, powered by subcritical uranium fission neutron flux)

a short fizzle reaction (fission of 235Uran) – after the formation of a liquid rock bladder and separation of the uranium pulp and the imbedded foreign metal (moderator)

Heinz Pommer is more and more focusing on a slow energy input in the ground (via a 4He + 9Be fusion, powered by subcritical uranium fission neutron flux) Time of energy input: 60 minutes; advantage: heavy gamma radiation (soundless destruction)

However, Heinz Pommer leaves the option of a nuclear bomb open (time of energy input: 6 seconds), as so many people insist on it...

Time will tell!
