I'm not from Sheffield and I'm not from Coventry and neither Coventry Airport nor Sheffield Heliport, come an Airport, are likely to turn a penny in profit for the foreseeable years ahead.
Sheffield Airport closed, Coventry Airport closed, someone with a bucket load of money re-opened Coventry but it may as well have stayed closed, so someone with a bucket load of money re-opens Sheffield ... With that length of runway it's likely to fare even worse than Coventry.
Boys and their toys!
