Services for Aviation (continued)

After a brief period in the Central Office Aviation Section with Walter Dwyer, John again became a squadron leader in the RAAF as OIC of the meteorological section of the RAAF station at Butterworth in Malaysia from 1960 to 1963. He then served as OIC of the meteorological office at Perth Airport after which he became Aviation Supervisor at the Perth Regional Office.

In 1973 John was appointed as the first Director of the new Papua New Guinea National Meteorological Service, a responsibility which he accepted and performed with his usual diligence and dignity.

A fitting tribute to John was paid by one of his former staff, Col Glendinning, in his reminiscences in Metarch Papers No 8, 1996. Col describes John as the perfect OIC who took great trouble in briefing Col when he first joined the aviation meteorological office in Perth.

Like many other weather officers John's lack of opportunity to take a university degree in science restricted his promotion within the Bureau but the significance of his contribution to the Bureau's service to aviation must rank him and many other weather officers among the major contributors in the Dwyer years.

Atomic Weapons Tests

After the initial explosion of an atomic bomb, Operation Hurricane, at the Monte Bello Islands on 3 October 1952 and some preliminary trials at the remote Dingo claypan named Emu Field in September and October 1953, two more atomic bombs, Operations Totem 1 and 2, were exploded at Emu Field on 15 and 17 October 1953. When the UK made a formal request for a permanent test site for atomic weapons in Australia on 30 October 1953, doubts were expressed regarding the risks to the Australian population from the fallout which had occurred after Operations Totem 1 and 2.

Nevertheless an Australian Department of Supply team had surveyed a possible test site at Maralinga on the Nullarbor Plain not far from Watson Station on the Port Augusta-Perth rail line, and reported favourably in February 1954. By 16 May 1955 work on the construction of an atomic testing range north of Maralinga had progressed sufficiently for minor Kittens trials to be conducted, followed in July of that year by further minor Tims trials.

However the Maralinga range development had not proceeded sufficiently for the testing of an atomic bomb and because the Emu Field site had been so contaminated by nuclear radiation as to make it unsafe for further testing, the AWRE was granted permission to use the Monte Bello Island site previously used for Operation Hurricane.

This was the situation inherited by Len Dwyer when he became acting Director of Meteorology on the retirement of E. W. Timcke in April 1955.
