Are you really saying that the building of those airports was not fueled by a load of dodgy backhanders? I know nothing about this situation, but I assume that any conspicuous wasting of public money must be corruption, the politicians cannot be so incompetent to make themselves look bad for no personal gain?
From wiki:
Castellón–Costa Azahar Airport
The company in charge of running the airport, Aerocas, was found to have spent 26 million euros, a sixth of the cost of the airport, on sponsoring various sports teams in its region. Also, a $375,000, 24-metre-tall statue, often interpreted as a representation of Carlos Fabra, the formerly powerful local politician who was the driving force behind its construction, was erected just outside the airport. Fabra has been under judicial investigation in connection with several cases of corruption and tax evasion, and was sentenced to four years in prison for tax fraud in December 2014.
