Inmarsat uses a Lisp application (G2) to monitor their satellites and to provide a high level overview of the status of all Inmarsat services in real-time.
If you would run a Cement plant, an oil pipeline or a coal terminal in South Africa, then you might also be using G2 to control and diagnose technical processes in real-time.
This application is written in 7+ million lines of Common Lisp
