Oban used to have two quite satisfactory runways and was capable of supporting the landing and take off of private aircraft up to and including small jets. It could also service small public transport aircraft to cope with the needs of the islands.
It had a well managed fuel service and radio which was enough to serve all the practical needs at modest cost.
As a result of local politics a fortune was spent which now means that Oban has one runway, almost half of which is unusable,
AFAIK it still has a well managed fuel supply capability, it has FISO who appears to believe that his primary role is to fill in MOR forms to no good purpose.
Thus the airport appears to be more expensive and less useful than before.
I'm pretty sure that all of the above is fact.
