Paris Orly airport had to close temporarily last Saturday after the failure of a system running Windows 3.1—yes, the operating system from 1992—left it unable to operate in fog.
French satirical weekly
Le Canard Enchaîné reported the failure, and
Vice expanded on the claims.
Orly uses a system called DECOR to communicate Runway Visual Range (RVR) information to pilots. In poor weather conditions—such as the fog the airport experienced on Saturday—this system is essential. Last Saturday it stopped working, and the airport struggled to figure out why.
