^^^ What he said - however:
The logistics of holding an air show involve providing accomodation for air/groundcrews and is dependent upon the influx of hundreds of Servicemen who also require accomodating. Waddington and Cosford use University Accomodation that is vacated during the summer months. I dont know what Finningley used to use, but can reasonably speculate that Mess' and barrack blocks that are no longer there were maxed out. If the RAF were unwilling to provide a (traditionally phase one student) workforce, the event is a none starter.
All hypothetical as I understand that as I type the meeting is taking place at Air Command that will conclude with a recomendation to CAS. Whatever the writing on the wall says, we are likely to find out fairly soon. Taxpayers prefer a tax hold and increased pay in their pocket to a day out watching aeroplanes and eating overpriced burgers. Without a dedicated budget approval .... Why is that chap putting a black hood over his head and picking up an axe?
