The answers given were, on the whole, what I was expecting.
Which brings me on to a further point.
Regarding the original Airwolf footage, what I expect happened was that the director briefed the pilot that he wanted the most exciting chase the pilot could produce. I think that going agricultural was completely unplanned.
The editor kept the footage in but cut away immediately after the rotors went through the bush so it is possible the pilot abandoned the chase as soon as it happened (probably very pale and in a cold sweat).
Are there any 'Oh my God, I learned a lesson from that' moments that others would like to share?
