The Forests Commission developed the use of helicopters for aerial ignition from the mid 1960s. Bryant and May at Richmond worked with the Commission to develop a Delayed Action Incendiary Device. DAIDs as the were known, had an overall length of 180 mm, striker end length - 10 mm. Ignition end length - 80 mm, then a layer of high melting point wax (to prevent accidental ignition when rubbing together in transit). Both ends coated with a modified match head compound with safety fuse exposed length between coated match ends. There was a 17-second delay from when the small end was struck to an intense flaming of the large end, which lasted for 40 seconds. DAIDs were dangerous so were stored in a metal box outside the helicopter along with a disposable striker patch attached with a quick release pin to a special half-door. The first test was with a Bell 47G on 4 October 1967 and the first use, anywhere in the world, of DAIDs to backburn a large bushfire was undertaken in north eastern Victoria in February 1968. There was a crash of an FCV helicopter conducting aerial ignition near Wandiligong on 19 April 1978 with the tragic death of two forest officers and their pilot. The crash led to the immediate end of the use of DAIDs and the adoption of the safer Premo ping-pong ball incendiary machine which originally came from Canada but was modified at the Altona workshops. Overall, the development of aerial ignition techniques by the Forests Commission from the mid-1960s resulted in a steady climb in the area burnt each year…. peaking at 477,000 ha in 1980-81 and with an impressive 10-year rolling average of 220,000 ha around the time of 1983 Ash Wednesday Bushfires.Developed in Victoria for aerial ignitionLarge double ended match used for aerial ignition and back burning by dropping from a helicopterbushfire, forests commission victoria (fcv)

Lorna Chick was a local artist whose works depict farming and community landscapes, which reflected her main occupation of living and working on the family farm with her husband and two sons. Chick was a naïve artist who used the aerial viewpoint as a constant device in her landscapes. Her naïve art style allowed her to distort the common notion of landscape paintings being horizontal viewpoints, bringing a different understanding to her artwork.naïve artRural City of Wangaratta Collection, purchased with funds from the Wangaratta Art CouncilA rectangular aerial landscape oil painting of a farming community overlooked by eagles painted using vibrant coloursObverse: LORNA CHICK ©wangaratta art gallery, lorna chick, landscape, farming, eagles, north east victoria, painting

Type used by RAAF Radar station (RS 14) for backup communications 1942 - 1946. This one is an AT5 radio aerial coupling unit with black face and dials and switches. They functioned as a set and were manufactured in 1938 at the Ashfield, Sydney workshop of AWA (Amalgamated Wireless Australasia Ltd, later AWA Ltd), Australia’s largest electronics manufacturer and broadcaster. They are rare outside Australia as they were seldom exported to other air forces, and remained in service until the late 1950s.202 An AT5 transmitter and AT5 coupling unit are held in Sydney’s Powerhouse Museum.203 The three units in the Wilsons Promontory Museum were deployed by the RAAF in WWII and represent the types of communications equipment used at the 14 Radar Station, Wilsons Promontory. It is not known, however if these particular examples were used at the lightstation and are part of the same set. They have interpretive relevance to the collection, but their significance to the lightstation is dependent on whether they have a direct historical association with the radar station that operated there. The units will have first level contributory significance if it is confirmed they were used at the Wilsons Promontory Radar Station.radio aerial coupling unit grey metal face with multiple dials & switches
