At the trials - for there will be trials, the questions will be, What would a 'reasonably minded' air-show organiser be expected to do to protect the safety of paying attendees, displayers, staff and people around the perimeter of the airfield? The same questions will be asked of the display pilot eg, How would a reasonable display pilot be expected to behave when performing his/her routine. The only people able to give evidence on those subjects will be air-show organisers and display pilots. The process will give a steer on how air-shows will take place in the UK in future. However, that will pale into insignificance when compared to the emotional pain the bereaved are going to feel. My thoughts are with them.
