I also strongly expect that most of us on here have “Freeloaded” at sometime in their lives. For example I grew up in the 1980’s very much under the flightpath of many of the displays at Biggin Hill and recall with fondness that on times when my family could not afford to take us to the show, we would watch from the house garden,or my bedroom window and occasionally the local park. When I left school and went to college in the 1990’s I would save up enough to go in for one day and stay outside the other. I would also when possible pay entrance for the arrivals day too( If wasn’t possible then I stood outside).
I accepted that there was a risk standing outside and always had in my mind the A-26 Invader crash which my cousin actually witnessed from outside the airfield when he was 12. However at the time this was the only way for me to enjoy the airshow and I saw some wonderful things that otherwise I would of missed, and I was fortunate never to witness an accident or incident during that time.

Since the mid 1990’s I have been able to afford to go to around 5 airshows a year and now always pay the entry fee no matter what,and since then I have sadly seen five fatal accidents four of which happened totally outside the airfield boundary. I personally feel the “Freeloading” thing is a difficult one as some people cannot truly afford the prices to get into an airshow,however the risk of an accident has to be thought of by those doing so, as there is always a chance that something could happen. If you can afford it go in and get the feel and atmosphere of these aircraft close up on the ground.
I really feel for the organisers of such shows as it would cost them a fortune to have “freeloaders” standing outside a show removed if even possible at all, yet if something does happen they potentially could end up at blame somehow.
