From a GA perspective Finningly is simply too expensive. The handling charge for a 172 is 78 quid and thus the place is dead. There is also a fair swell of opinion that once Peel has got the council to pay for all the roads to be redeveloped the place will close and morph into industrial units as well.
Nottingham Tollerton exists yet EMA only 12 miles away. So it can be done. You also only have to look at some where like Staverton which appears to be going from strength to strength and I would say Sheffield has a much larger population.
But then that’s missing the point the place was doomed from the moment it was sold for a quid with the proviso that it can be redeveloped after 10 years.
