The Pilot came to me just before this flight and told me what would be the
best viewing position for this shot. I wasn't convinced but as the weather
was crap, I decided I'd do it for him his way. after all, his routine was
worked around where the crowd centreline was He then turned in front of me
thus hazing the entire sequence. Next time I'm back to my position :-)

But it's an interesting effect if done once every ten thousand images ;-)
