Ansett 727LR......
As far as I know, Ansett was the only operator of the 727LR, their four aircraft were the last passenger versions built before Boeing completed an order for 50 727 Freighters for FEDEX and ended 727 production....had some time in the 727 and normally flew at .82..enjoyed the occasional descent at
350 KIAS to 20 miles, in Australia the 250 below 10,000 was only introduced in the early 90s and many controllers were quite happy to issue a waiver if requested, I believe the MEL-SYD record was set many, many years ago, departure off RWY34 MEL, arriving RWY07 SYD, this was well before they introduced all the fancy STARs with lots of extra track miles, impossible to equal it these days.
