As a plane guy, I can often be a bit dismissive of the non plane related things that are brought to air shows. I do realise that making an appealing day out for everyone is necessary and I am in the minority. The Shuttleworth show had some performers in the crowd to amuse the visitors. There were two women that were walking through the crowd on stilts. They were keen to engage with everyone which, of course, is what they are there for.
Additionally, there was a guy creating large bubble clouds. The kids were certainly loving these and I suspect a few adults were too even if they were pretending it was all for the kids. I love bubbles so I bet they might too.
