I watched it with an open mind.
Aside from the obvious Essendon calls whilst showing aircraft at Moorabbin, the small captioning error and the Jabiru used for the cockpit scenes
I think it was PERFECTLY VALID.
Just imagine what the thread will look like when someone crashes due to poor unreadable english, things will be different then!
For those instructors that think the foreign students are ok, you need to get out of the Moorabbin training area (for example) when they go on Solo Nav's and have a listen to the VHF. Whilst you're having a listen, try switching to 123.45 or the other random channel that they choose and you'll here as much foreign language between aircraft than you'd hear in little China town (for example). I heard a call on the weekend that I could not understand, with the exception of the field that was to be overflown and I work with foreign people of all the usual suspect countries daily.
