Australia’s domestic jet age began 50 years ago today

I always thought the DC9 was the jet aircraft that first began Australian domestic services? Just like the story describes, both airlines had theirs on the ramp at the same time. I loved those funky rear air stairs. The B717 we have now give me a nostalgia kick when I see them fly over. They're incredibly quiet inside too, but no more air stairs instead just an emergency chute after the tail cone falls off!
