As a kid in the early seventies I lived on Pascoe Vale road, at the flats across from the Oak Park swimming pool. Every 3 to 5 minutes an aircraft would fly over and it would be enough to shake the foundations and move all the pictures on the walls!
Mum would dutifully straighten them and then the same thing would happen again five minutes later.
Those were the days!
Bring back the JT3D I say, God's own engine...
