Trevor James Constable

In 1991 Constable worked with the local Malaccan government on a project to fill the Durian Tunggal Dam.

The Malaysian government eventually began a probe into TJC/Atmos Engineers to look into whether there was any evidence that the State government had been cheated. In total the local government had paid them $3.2 million. However, the following was reported on Aug 14, 1991 in the New Straits Times, "TJC Atmos Engineers was hired by the Malacca Government to solve the State's water problems by filling up the 28-metre Durian Tunggal dam which dried up in January. They will be paid $3.2 Million if they succeed and half if the dam is half full by the end of next month. The operation started on July 1. Mr. Constable described the contract to undertake the operation in Malacca as totally contingent - no result, no pay." It would appear then that if the Malacca Government paid out the full amount of $3.2 Million to TJC/Atmos Engineers, that they would have been deemed to have fulfilled the full contractual obligations for receiving that sum of money.

The biology of the creatures supposedly meant that they were visible to radar, even when not to the naked eye. To explain supposed cattle (and occasionally human) mutilations, Constable theorised that the use of radar angered the organisms, who would become predatory when provoked. At a later date a crypto-zoologist officially classified these supposed creatures as Amoebae constablea, named after their discoverer. Constable wrote a book entitled The Cosmic Pulse of Life in 1975 that outlined his ideas.

The historian Jens Wehner notes that the 1971 book by Constable and Toliver on Hartmann, published in German as Holt Hartmann vom Himmel! Die Geschichte des erfolgreichsten Jagdfliegers der Welt, was immensely popular in Germany, but contained serious flaws in terms of presentation of historical realities. These included the uncritical borrowing from the Nazi propaganda elements of the Fliegerassen ("aces") and stereotypes about the Soviet Union. According to Wehner, the latter could be traced to the prevailing attitudes during the Cold War. Further, the political and social consequences of World War II were completely ignored.

Trevor James Constable (17 September 1925 − 31 March 2016) was an early UFO writer who believed that the UFO phenomenon was best explained by the presence of enormous amoeba-like animals inhabiting earth's atmosphere. A native of Wellington, New Zealand, he served 31 years at sea, 26 of them as a radio officer in the U.S. merchant marine. He authored several books on the aerial warfare of World War II, together with co-author Raymond Toliver. These works have been described as uncritical and not grounded in historical realities by several historians.
