I only came on here to wish Sheffield Forum Happy Birthday, but I have to pass comment here. I did post extensively on the other Sheffield Airport thread several years ago but, to recap:
Sheffield Airport regularly had business jets visiting - Learjets, Citations, etc
Sheffield Airport had several aviation related businesses operating from there (helicopters, flying schools, etc) I know, I worked for one of them
It always struck me as being a strong selling point for the Business Park to have an airport and a motorway next door. Not many business parks can say that. Indeed, several of the original tenants of the business park were there precisely because of the airport
Th reasons for Sheffield's closure are well rehearsed (the joint ownership of Doncaster, the inheritance of prime land for £1 if Sheffield could be shown not to be viable). It could have been (and was) a thriving business / GA Airport.
I lost my job with a helicopter flying school and charter operator which was based at Sheffield City Airport. That company no longer trades - the airport it used to operate from no longer exists.
I now work for a major helicopter charter operator and flying school based at a thriving airfield on the South Coast in a city which is 10% the size of Sheffield. The airfield thrives - but there is no holiday traffic!
I get enquiries to fly people to the Sheffield area by helicopter, but that is difficult. There is no air/ground radio, no fire & rescue facilities, no fuel. If we are flying in the area, we have to go to Gamston, Nottingham or Leeds for fuel. If our client asks to be flown to Sheffield it is not sensible to offer to fly to Doncaster instead - a 45 minute drive each way on either end of a flight which will take little more than an hour from London does not make any sense.
If Sheffield City Airport re-opened, even as a heliport only (with radio, fire & fuel facilities), I am sure I would be sending helicopters there before too long. And I am sure that it would benefit Sheffield and South Yorkshire to have a proper Heliport facility. At the moment there is no such facility between Nottingham and Leeds - a large gap on the aviation map!
