St. Athan? Airfield is now civilian, relatively good communication and infrastructure.
Surprised by statement from IWM, ok, it's a war museum first, however with a large aviation content, TFC are by definition warbirds which makes the IWM statement a little contradictory.
Disagree with the 'niche' statement, run two shows, flying legends and ' generic' and compare gate receipts; difficult to understand IWM rationale on this.
