Must have been on training flights, how dreadful for the families concerned, especially at this time. Unfortunately there will be now a rush of "close Bankstown" even if the airport was there long before the population gathered around it. Bankstown of course being the training ground for thousands of us over the years, as well as a busy GA base, serves aviation needs well, but a terrible accident like this brings it into the public eye. My condolences to the families concerned for the loss of two young pilots who had so much to look forward to.
