They are hiding it behind 'concerns over costs'
Hard truth for them is, the 'military fest' is what general airshow attendees go for. People want to see the Red Arrows and the Typhoon as to them, they are the 'heavy metal' to them. They want fast and loud jets
Portrush in the last few years became all about the props and family friendly aerobatics in Pitts Specials and Vans RV7s. Absolutely nothing wrong with those displays but the fact is, they don't bring the crowds in, as evident in the dwindling numbers to Portrush between 2016-2019.
The 'certain parts of the community' thing is just BS (sorry) In my experience running the AirshowsNI page, and the Newcastle FoF page over the last 6 years, there is no community divide over it and very few feel uncomfortable. In fact, I've only had ONE complaint about this in 6 years. The main complaints I actually get are more to do with animal welfare during the shows due to noise.
The vast majority support it and MANY from what they describe as 'certain parts of the community' actually love the show.
Sad truth is, this political party who will remain nameless, just don't want anything that doesn't align to their side or viewpoint.
Sorry, rant over.
