Greetings,fellow fliers. I'm a 1st time poster,long time reader. I,too,was a DC9 pilot with Australian Airlines. For you youngens,we flew those excellent aeroplanes all over Australia with ADF,VOR & DME. No GPS in those days. If the Cooyong NDB was U/s,we had to use a lot of cross bearings to keep on track to Melbourne. The DME had no ground speed readout,so to know how fast we were going,we would see how far we went in 36seconds & the multiply by 10. Ahhh,the memories!!
