Long ago I loved going to air shows and even displayed for a few years, so I'm sad to say that I think Shoreham marked the beginning of the end for them. The free and easy atmosphere of those days has gone the way of the uncontrolled airspace where I once spent many happy hours in attitudes which would likely alarm the Airbus and Boeing drivers who daily plod their STARS and SIDS.
Throckmorton is or was a charity show organised by volunteers who appear to have been personally liable in the event of anything going wrong. If I was one of them I too would try and indemnify myself against the inevitable claims. Please don't be so hard on them, folks, they did their best but I fear the insurance premiums would far exceed the likely revenue.
