I've suggested things like this before, both on here and elsewhere. But "blue sky thinking" is ultimately pointless, as nobody has any power to influence the RAF's thinking. They'll do whatever the bean counters and
PR people recommend, and we can all make a fairly good guess at what will happen - a few noises about maybe having another Waddington show if we're lucky or (more likely) a decision to abandon all shows and put their support behind RIAT. Any other outcome seems distinctly unlikely.
Personally, I guess I'm just lamenting the loss of all the RAF's air shows, but I don't imagine there's any way out of this. In an ideal world we could look at staging a really good show at a suitable base, be it Cottesmore or elsewhere, but it's not going to happen of course. If a show of any sort survives it will be quite a surprise I think.
