Exactly Pete, you can't mitigate against the absolute certainty of bits falling off aircraft or a full blown accident. If it's going to happen, it will - and does. Today in the UK, X number of people will be killed on the roads, X number of people will be killed in their houses doing DIY, etc, etc.....That's life unfortunately.
All I will say is that this event will be a complete gamechanger for displays in the UK.
