I think that this could be a good idea, many G.A pilots like Sheffield just how it is and ever since commercial sceduled traffic has gone the airport has made up for its lack of commercial traffic, its a popular destination for many PPLS alike.
Ga traffic would cope with the runway being cut, some commercial traffic wont but then again many who are based there dont want commercial to come back.
Read the latest report in todays pilot about the airport.
Then again what do I know;)
