An "AIRPORT" of any viability shouldn't need to give two hoots to "Airfix Kits" such as PA28's and Cessna 150's that pay how much per landing fee?
This area is for Airlines, Airports & Routes, not flying clubs and Airfix kits!
I guess we should now realise that Sheffield City shall be seriously viable once it may re-open because it hopes for Piper and Cessna movements and "We'll show DSA what for"
