The underground installations were amazing. They were literally subterranean towns. There were four in and around Ohrdruf: one near the horror camp, one under the Schloss, and two west of the town. Others were reported in near-by villages. None were natural caves or mines. All were man-made military installations. The horror camp had provided the labour. An interesting feature of the construction was the absence of any spoil. It had been carefully scattered in hills miles away. The only communication shelter, which is known, is a two floor deep shelter, with the code "AMT 10".
Over 50 feet underground, the installations consisted of two and three stories several miles in length and extending like the spokes of a wheel. The entire hull structure was of massive reinforced concrete. Purpose of the installations was to house the High Command after it was bombed out of Berlin. This places also had paneled and carpeted offices, scores of large work and store rooms, tiled bathrooms with bath tubs and showers, flush toilets, electrically equipped kitchens, decorated dining rooms and mess halls, giant refrigerators, extensive sleeping quarters, recreation rooms, separate bars for officers and enlisted personnel, a moving picture theatre, and air-conditioning and sewage systems.

If the structure was built like a wheel, the Führer headquarters would logically be at the hub, and Amt 10 was at the hub. Allen's description of Amt 10 as having two floors on April 1945 conflicts with the evidence of two persons who worked there: one hinted that there were more than two floors, the other testified there were three. The latter witness also stated that Amt 10 was two great bunkers of the same size, each of three floors, but not connected except by underground piping. Each bunker was guarded on each level by an SS sentry and passes for each entrance were not common to both. The most likely explanation is that the second bunker was constructed in 1944 at the same time as a third level was added to the first Amt 10 bunker as the Führer-suite.
As regards the second bunker, a witness stated that in 1944 there was an installation below the Ohrdruf Truppenübungsplatz which created an electro-magnetic field capable of stopping the engines of a conventional aircraft at seven miles. During the war, the Allies never photographed Ohrdruf from the air, nor bombed it, even though their spies must have assured them it was crawling with SS and scientific groups. A German electro-magnetic field which interfered with their aircraft at altitudes of up to seven miles is admitted by a 1945 United States Air Force Intelligence document . The USAF suspected that it was a device to bring down their bombers, but it obviously had some other purpose, or it would have been operating below Berlin.
Many Arnstadt witnesses described occasions when electrical equipment and automobile engines cut out. They always knew when this was about to happen, for the ship's diesel engine at Amt 10 would smoke. A diesel motor is not affected by an electro-magnetic field. In 1980, Russians scientists were still able to measure the field on their equipment, but they were never able to identify the source.
A technician, who was interrogated after the war, told the tribunal that there was a power supply that needed no fuel and the diesel units where only for emergency backup. Another witness claimed shortly after the war that they had been told by someone at the base that there was a Tesla energy device. Many of the locals in the villages reported that there were weird electrical discharges across the ground of the valley. Some of these have continued to be sighted to this day. Also electrical devices occasionally fail temporarily across the valley and cell phones seem to sporadically fail in the area. Some researchers believe that this is because the power supply is still buried underground and the Germans sealed it away prior to the allies arriving in the area. Some believe that the power supply used is still functioning intermittently. The Russians spent many years searching the area and never finding the source of the magnetic fields in the are and the odd discharges.

The report states that during 1944, an explosive mixture of 60% liquid air and 40% finely powdered coal dust invented by Dr. Mario Zippermayr was tested at Doeberitz explosives ground near Berlin, and was found to be very destructive over a radius of up to 600 metres.
Waffen-SS scientists then became involved and added some kind of waxy substance to the explosive. The bombs had to be filled immediately prior to the aircraft taking off. Bombs of 25 and 50 kgs were dropped on Starnberger See and photos taken. Standartenführer Klemm showed these to Brandt (Himmler's scientific adviser). The intensive explosion covered an area up to 4.5 kms radius.
This waxy substance was a reagent of some kind which was said to interact with air during the development of the explosion, causing it to change its composition and so create meteorological change in the atmosphere. A lightning storm at ground level consumes all the available oxygen. Göering's statement upon his arrest in May 1945 is significant: he claimed to have led a revolt against Luftwaffe use of a bomb "which could have destroyed all civilisation." The bomb was not a nuclear weapon, and it appears to have been a conventional explosive which used a reagent or catalyst produced by Tesla methodology or similar for its inexplicable effect.

since before the war 200 SS scientists had been researching Earth Sciences in an underground laboratory at Stechowitz on the Czech border, and what all these scientists discovered is unknown. The Waffen-SS Pionierschule was near Stechowitz: at the end of the war all lower grade technicians and SS men there were executed by a Wehrmacht death squad under a Major Lange. Besides Ohrdruf, there was a similar underground centre working on Aryan plasma physics at Waldenburg in Poland. Here too, at the end of the war, even German staff were murdered. This information came to light from the recently declassified depositions in the case of The Polish People v Jakob Sporrenberg, an SS-Obergruppenguehrer charged with the 62 murders.

The search for a conventional German atomic weapon will never bear fruit. The last search made for FKpt Falk or Falck was 1999 when I was member of a forum of scientists and writers investigating the U-234 mystery. All crew members and passengers aboard U-234 except Falk were returned eventually to Germany. Falk was kept segregated from the other passengers while in captivity. The report on his interrogation states that he was relaxed and talked freely. The Office of the Wehrmacht Fallen and the German land authority controlling the return of PoWs from abroad have both reported no trace of FKpt Falk. An American lawyer who ran the 1999 forum stated his opinion that it would not be possible to release an alien prisoner into the United States without some documentation. Even under the Freedom of Information Act the United States authorities have managed to avoid answering the question as to his whereabouts after 26 May 1945. Lt Pfaff was still alive two years ago. After unloading the ten containers from U-234 for them, he was sworn to silence by the US authorities and immediately awarded US citizenship, as was the boatswain who assisted him, Schoelch. From this, it seems logical to deduce EITHER that Falk knew too much and could not be allowed to live with the information OR he was offered the same deal as Pfaff and Schoelch and refused it, his murder then ensuing.

On April 17, 1945, the United States Atomic Energy Commission inspected various underground workings at Ohrdruf, and removed technical equipment before dynamiting surface entrances. The US authorities have classified all 1945 documents relating to Ohrdruf for a minimum period of 100 years.
