[The following is an extract from an email from Håkan Håkansson of the Department of Cultural Sciences at Lund University, Sweden. It provides a useful reappraisal of one of the references we site in G:TT to support the possibility of sonic levitation being used by the ancient Egyptians - to the work of Henry Kjellson]

Dear Mr. Lawton and Mr. Ogilvie-Herald

…You refer to the Swedish engineer and aeroplane constructor Henry Kjellson (1891-1962) in connection with the possibilities of "sonic levitation". I haven't had the opportunity to read Andrew Collins' book, from which you seem to have drawn the information, but in the 1960s Kjellson earned a reputation as something of a Swedish Erich von Däniken. In his "Sju nätter på Cheopspyramidens topp" ("Seven nights on the crest of the Great Pyramid") Kjellson describes how he by means of a "Tibetan breathing technique", performed, yes, on the top of the pyramid, was able to communicate with the spiritual side of our existence, which guided him in his quest for the truth behind the pyramids-which seems to have been that they served as "laboratories" or possibly "nuclear reactors" 30.000 years ago. How this is compatible with his conclusion that the human race at that time was a "race of giants"-evident, he notes, from both the Bible and the height of ancient temple doors-is not entirely clear, since this implies, as he correctly points out, that the builders were too tall to enter the pyramids once they had built them. In any case, he claimed to have found traces of radium in the pyramid, proving that it had served as a nuclear storeroom until Moses eventually stole the radium and brought away to Jerusalem in the Holy Ark.

The book "Lost Technology" ("Försvunnen Teknik"; the title given in your book seems to be a Norwegian translation) in which he describes "some ancient Tibetan technologies" is more or less in the same spirit. Here, however, the spiritual guidance has been replaced by anonymous friends whose eye-witness accounts have been as hard to verify as the existence of the friends themselves. The story of "Dr. Jarl" is a strange tale of how this doctor of medicine in Cairo was visited by some mysterious Tibetans who brought him to an unknown Himalayan monastery, at which, it turned out, an old friend from his Oxford days had become abbot. Obviously the monks were in need of medical help from this Swedish doctor, despite their ability to travel in time and space, to create unknown substances ex nihilo, and to mentally project huge moving pictures on the walls, on which past events could be seen "just as on a television screen". The chapters dealing with "sonic levitation" describe perfectly traditional ritualistic instruments and Kjellson's "scientific analysis" of how these instruments might have worked is on the verge of unintentional travesty: to lift a 6.3 ton block of stone 250 metres in 3 minutes requires 117 horsepower, but since a human being on the average can produce only 0.75 horsepower, the thirty drummers and trumpeters aren't sufficient unless the instruments can "provide a superhuman power"- which they obviously do in some inexplicable manner. How the sound actually creates the necessary underpressure to lift the stones is left to the imagination, and the film "Dr. Jarl" claims to have taken of this technique put into practice has, of course, never been shown to anyone, not even to Kjellson…

Yours sincerely
