A Control Joy Stick presented to Pilot Officer Eric V. Read in 1937 after it was recovered from an aircraft he was flying had crashed in the Brisbane Ranges in December 1936. Eric Read was a 21 year old RAAF pilot who was on a flight over the Bacchus Marsh region to make meteorological observations. Read's plane came down in bad weather and crashed into a heavily wooded area of the Brisbane Ranges between Staughton Vale and Mount Wallace. An extensive air and ground search was conducted and after 32 hours Read was located, alive, but badly injured and unable to get out of the cockpit of the plane. He was first located from the air and then a rescue party was able to reach him through rough country and bring him to safety. Read recovered from his injuries and many years later gifted the control stick of the aircraft he had been flying as an item for the collection of the Bacchus Marsh and District Historical Society.This item is of local historical significance as an object related to a notable aircraft accident and subsequent rescue of the pilot. It is also significant for its rarity as a surviving piece of aviation equipment from this era.Control or Joy stick mounted on a wooden base.aircraft, aircraft accidents, eric v. read

This is a set of 19 photographs taken in 1989 during 4th Field Survey Squadron’s deployment on Operation NERIGHT 89 in Queensland and the Northern Territory. It was a two-part operation in 1989 with work conducted in the areas of Camooweal and Weipa. Part 1 was the field completion of topographic maps conducted near Camooweal QLD, along the Barkley Highway on the border between NT and QLD, from the 12th of September to the 20th of October 1989. A Bell Kiowa LOH helicopter from 162 Recce Sqn supported topographic field completion. Operation NERIGHT 89 Part 2 was the acquisition of mapping control by GPS field parties utilising Texas Instruments TI4100 Global Positioning System receivers around Weipa on Cape York Peninsula from the 22nd of September to the 22nd of October 1989. Part 2 Two Bell UH-1H Iroquois helicopters from RAAF’s 35 Squadron were principally used to deploy GPS field parties. Identification photography of control points was taken by air camera operators in AAAvn Pilatus Porter aircraft from 173 Gen Spt Sqn fitted with an RC10 aerial camera. The two parts of the operation were conducted concurrently. This is a set of 19 photographs taken in 1989 during 4th Field Survey Squadron’s deployment on Operation Neright in Queensland & the Northern Territory.

This is a set of 30 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967. Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds.

This is a set of 16 photographs taken during 4th Field Survey Squadron’s deployment on Operation ARIGHT 91 in Queensland from the 8th of July to the 5th of September 1991. The area of operations was the top end of the Cape York Peninsula, islands of the Torres Strait and the southern coast of PNG. Field parties utilised Texas Instruments TI4100 Global Positioning System receivers. Concurrent with GPS operations Doppler point positioning observations were carried out by field parties using Magnavox MX 1502 receivers on six of the control points. Two Bell UH-1H Iroquois helicopters from RAAF’s 171 COMD and Liaison Squadron were primarily used to deploy GPS field parties. Identification photography of control points was taken by air camera operators in AAAvn Pilatus Porter aircraft from 173 Gen Spt Sqn fitted with an RC10 aerial camera.This is a set of 16 photographs taken in 1991 during 4th Field Survey Squadron’s deployment on Operation ARIGHT in Queensland.
