Same could be said about Luton, as it has debts of over £500m and lost over £100m last year but is supported and bailed out by the council. The parent company of Doncaster will not let the airport go bankrupt, as the land is worth more than the debts so remains a valuable asset. Yes they can shut it down but that is not the same thing. It will then be put under care and maintenance for other uses. With no staff apart from a man and a dog costs will drop off a cliff.
