4Greens,
Why did you do it ----- because everybody joining QF had to do their time on -EDC or -EDD.
The prevailing wisdom, at the time, was that if you couldn't fly a Dak, you were undoubtedly a poofter, a dunce and Yetti 3rd Class, and certainly not a real pilot.
For blokes who had never flown a tail wheel aircraft before, we generated some lovely rubber marks on the runway at Tamworth, off the edge and back on the runway a bit further down.
And, as even ex-military pilots discovered, your performance on the Dak. determined whether you were assigned to the DC-4, Electra or straight to the B707.
Tootle pip!!
