If we limit air shows to straight and level flight are we really reducing the risk? Aircraft are fatally lost in take-off, landing and straight and level manoeuvres as well as aerobatics. I can think of several aircraft that have been lost in hanger fires.
Where do we draw the line ?
If we make air shows boring gate attendance will reduce and they will cease to operate.
We have to put faith in the operators and pilots that sufficient has been done to minimise any risk,
and accept that some risk will always exist.
Since 1989 I have personally witnessed 3 accidents only one of which was fatal.
We hear about the accidents, no one mentions the thousands of hours of safe flying.
