Mike Scanlon had an interesting history article in the Newcastle Herald this weekend (22 October 2022), on the mystery of the forgotten World War 2 runway at Pokolbin. In 1942 the RAAF built an air station at Pokolbin. The north-south runway was located where the current Cessnock airport is now. But there was also second runway located towards the south-west.
In the article Mike mentions that this old east-west runway can still be seen in Google’s satellite views. Using the historical imagery feature in Google Earth Pro and winding back to 2007, indeed shows a faint yet quite distinct outline of the old runway lying beneath fields and vineyards.
