The mighty B727. It was faster than the RAAF's front line fighter in 1964; the Vampire.
It was interesting to see the B727-100 operate on the short 17/35 at Essendon for 6 years or so before Tullamarine was opened to domestic operations.
I hear there is a lunch at Essendon Airport on Friday 17 October to celebrate the 50th anniversary of the arrival of the first B727 in Australia (16 October 1964)
