The Sunnyvale airstrip is west of the town of Henty. VH-FLE was using it as base while spraying aphids on farms nearby. The engine has been left running, turning the prop slowly, as the chemical mix is prepared.
VH-BTX was still officially registered at the time of the photo. It was stored among the wreckage of several agricultural aircraft, a battered Enstrom VH-IPE, several old cars and sundry building materials. -BTX was registered in 2009, an import from the UK where it was G-MHCI.
