Just remember that the lack of an accident does not translate to - It was safe.
This was one that caught my eye and if this photo was taken from a similar position to other photos, then I would expect a similar attitude to the other aircraft. Mind you I haven't seen the H/V curve for the B407 and it might be fine to be travelling at this speed, accelerating and at that height.
I'm glad that everyone had a good time and an incident free time.
I have flown into the F1 and bike GP's in Melbourne more than once, and this turn out puts us to shame. Congrats to the organisers and controllers. Job well done.
Fantastic photos.
