Has any fault been attributed to the show organisers?
A good question Girls with wings, and one which I suspect will occupy the Coroner and may feature in any civil proceedings.
That a display might go wrong, for whatever reason, is all too obvious, and history is strewn with examples which have led to crashes (including at Shoreham not so many years previously).
Factor in Fast Jets and high energy, and not much imagination is required to foresee the potential for an outcome such as that which so tragically unfolded at Shoreham. The risk assessment for the event must surely have conducted some evaluation of the likelihood of an accident and the potential consequences thereof. IMHO, to reduce the residual risk to an acceptable level given the likely catastrophic consequences of the risk occurring, a ridiculously optimistic probability would have to have been attached to the likelihood of the risk occurring.
Put differently, even a perfect pilot flying a perfect aircraft in a perfect manner represented an unacceptable level of risk flying that display at Shoreham given the potential for disaster if something did go wrong.
