One could easily ask if the industry has changed much over the last 10, 20 or 30 years...?
Certainly there has been change, much of it brought about by technology, wizz-bang systems and lots of buttons to push.
Pay and conditions have changed, but at the end of the day you take what you are happy with or the best available or you go somewhere else.
Training is certaily nowhere as good as it used to be and it shows, right thru from GA to airlines.
DCA/DoT/CAA/CASA/Airservices have all changed. Bring back DCA I say, but those days have long gone!
