The five were clearly sent to their deaths because of the totally rediculous RAAF airspace restrictions that existed on that Sunday night when no military operations were taking place at all.
Ok Dick, then answer the direct question regarding VH-AZC. Why was this aircraft also not 'sent to their deaths? Same planned destination (YSBK) almost identical aircraft, separated by about 10 minutes.
If the RAAF are the problem, why is there not a C206 as well as a C210 up there we are looking for?
Now, I go back to my original question, that you are dodging -
If the US NAS military airspace had existed at Willy that night the pilot would have continued down the coast with lights and a horizon in front.
But, it didn't exist, and yet in spite of that, a C206, VH-AZC, planned, and flew that route with "lights and a horizon in front." MDX and AZC was, incidentally, not the only traffic operating in, over or around Williamtown then.
If what you are saying is true, then the above statement shouldn't have been possible. Could you please reply to that statement.
Answer that question, using the aircraft in question as an example.
