 The site chosen for 5 SFTS was especially suitable because it was on the main Sydney to Melbourne railway line and comprised just over of land that was owned by the Lewington family.Possession of this land was taken under National Security (General) Regulation 54 which existed during the War years.On 7 April 1942, a Wirraway of 5SFTS crashed during an instrument training flight at the Air Ground Gunnery Range, killing both crew members.
