I spent my first 30 odd years a mile or so east of the E - W runway at Essendon. At this time there were all manner of interesting planes to see. The airport was separated from the surrounding paddocks by a few strands of fencing wire and we used to ride our bikes to watch the planes lined up waiting takeoff.
To do anything similar these days one would be shot on sight. But those were the days when we could wave to Pilots and Engine Crews and they would reciprocate. Who says it was not a better world in those regards then?
In the early days most prolific were, of course, DC3s plus DC4s, Convairs and Bristol freighters. Later came DC6s, Viscounts and Fokker F27s. Later still Electras, Boeing 727s and DC9s. The few overseas flights were Electras to NZ, BOAC Comets and QANTAS Constellations to London.
People moan about aircraft noise but when everything went to Tullamarine we really missed the planes and it was eerily quiet.
On the rail side we still had the Spirit of Progress to make some noise until 1962. Up to the early 1950s, of course, the SoP was still steam hauled. A sight to behold!!!!!!!!!!!
