LBIA
The west Yorkshire public are no fools. You drive past that airport and visually the airport has literally not changed in 30+ years since the runway extension. The only outward change is a tin weather shelter.
If the public saw that the owners were serious with the shown masterplan 'plans' then they would get behind their airport even more. Their really is a feeling of complete inertia as regards progress at LBIA that literally pushes locals to fly from a nearby airport that does spend money up front on attracting them (including putting up posters).
