Anytime I see a thread that Dick has started or even added to I enjoy the reading the replies etc, love the few same suspects that run Dick over by bus cause he gives an opinion different to them, that's entertaining:-) TEM, that's the 'IN' word these days, there's industries set up around it & is a subject that has a mythical aspect to it. In my opinion two of those threats are ATC & CASA, we are lucky (if that's what you want to label it as) here in OZ that the WX is mostly benign, training is reasonable & the skies not crowded but we do have the aforementioned two threats/risks.
Continue on Dick, you do add value to our aviation scene despite what some say:-):-)
